I have a ASP.NET Core with Blazor website and I want to deploy it to Arvixe host. The website is very simple and contains only UI elements no database required. I published the website to a local file system and uploaded it using FTP to the Plesk.
When I am visiting the website, I receive this error:
500 - Internal server error. There is a problem with the resource you
are looking for, and it cannot be displayed.
I have tried to run it on the IIS and I received more details:
Configuration The configuration file cannot be read due to
insufficient permissions.
I tried to add IIS_IUSRS to the group and users for web.config but I am not able to find it because I am using a windows 10 connected to active directory.
Besides, I still don't know how to solve this problem at Arvixe. Does anyone know tips might help?
500 internal error is generic issue. Please kindly check the error message on the server and paste it here. Make sure that your provider has installed .net core bundled on their server and here are tutorial about publsih .net core using plesk https://windowswebhostingreview.com/how-to-publish-using-web-deploy-with-plesk-control-panel/. It should be working fine.
You need to give Full Trust permission (Read-Write-Execute) to your application folder and also to Application Pool and also check if the Runtime version supported by Arvixe matches with your Asp.net Core version.
Also enable the logs in web.config file by setting stdoutLogEnabled="true" to get detailed error so that you can investigate more about the error.

I am trying to deploy my Website with umbraco 10, I always get the following error:
HTTP Error 500.30 - ASP.NET Core app failed to start
The website works correctly locally, however when deploying the app I get the same error...
Details:
DB SQL Server
Azure WebApp .Net6
What i have tried
I have followed the instructions: https://our.umbraco.com/documentation/Fundamentals/Setup/Server-Setup/azure-web-apps
I have created a project from scratch, thinking that the problem was some package, but still the same error.
This is how my umbraco 10 application looks once deployed from VS to an appservice (Azure)
The first thing I would do is check the logs on the the environment where you have deployed the code. That should give you a better idea what is actually going wrong as the error you are getting is very generic and not that helpful.
I have seen issues where the media folder is missing and that is something to check.
When I have issues in Azure, I also look at the files via the Azure Portal and check the connection string and any other configurations files to ensure they look correct. It could be the deployment has screwed up some values.
Have a look at this post which may provide some further details - https://our.umbraco.com/forum/using-umbraco-and-getting-started/108288-getting-http-error-50030-after-successful-publishing-to-azure
I have this Asp.net Core 3.1 developed on VS2019 preview.
basically it is a blazor server-side app with referenced assemblies and some nugets.
it runs fine on VS2019 and on my IIS after publishing to folder..
problem is when i move that folder to windows server machine with IIS installed and everything.
an error with 500 code appears.
one thing i noticed here..the log_error.txt file in the server it points out an exception
,and that exception -what ever it is- showing the error line of the startup.cs file with my laptop directory path !
i mean it shows this C:/mrmeeez/..../Startup.cs line 411
but this path does not exists in the windows server machine
it supposed to be F:/.... somthing/Startup.cs line 411
i don't know if it has something too do with the problem anyway..or maybe my assemblies and nugets not shipping correctly to the server
windows server machine is working fine , i tried blazor app template and it ran perfectly.
i need your help guys , Thanks !
Ok , i found it
i don't know for sure is this related to asp.net core 3.1
because i deployed asp.net core 2.1 months ago and it was fine
anyway i used the development exception page in the final publish to see what causing the error and showed this
UnauthorizedAccessException: Access to the path 'C:\Windows\system32\config\systemprofile\AppData\Local\ASP.NET\DataProtection-Keys' is denied.
and after searching for that i found the answer from a guy in github
it seems that the user IIS_IUSRS for this application pool -by default- does not have permissions to access that path
to solve this problem,either one of the two below:
1-Give IIS_IUSRS permissions to access the system files -NOT RECOMANDED-
2-Change the user of the your application pool to LocalSystem account in IIS by going to Application Pools -> Right-Click your app -> Advance Settings -> Process Model section then change Identity

Thanks!
I am trying to publish as ASP.NET Core project with a hosting provider that supports ASP.NET Core. I am getting 500 Internal Server Error which I believe is very common. So I searched through the internet and various forums and then I checked the processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" in web.config and they look to be correctly converted with processPath="dotnet" and arguments=".\MyApplication.dll".
I also checked the connection string and it points to production DB server that's working. I confirmed the DB connection by changing the connection string to production DB and running project local. It works and I get the production DB access.
I also tried to get the error info by using the below in my Startup.cs (irrespective of env):
app.UseDeveloperExceptionPage();
app.UseDatabaseErrorPage();
app.UseBrowserLink();
I have also enabled stdoutLog in web.config, but I don't see that folder either:
stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout"
I also tried to change applicationUrl and launchUrl in launchSettings.json to my prod Url, but that didn't work as well.
So, the 500 Internal Server Error refuses to go away, and I still don't have a useful error message. The page just says:
Oops.
500 Internal Server Error
An error occurred while starting the application.
I would really appreciate if someone could help me here.
I have also enabled stdoutLog in web.config as but I don't see that folder either:
stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout"
There is one trick here - you must create both folders logs and stdout manually - then and only then IIS will create log file inside logs folder (not stdout as you could expect) - don't ask me why, because I don't know why ;)
Oops. 500 Internal Server Error An error occurred while starting the application.
Usually, means problems with a configuration in Startup.cs - the most common problems include an issue with DB itself, an issue with migrations (if you are using Code First approach), problems with appsettings.js, problems with Social Logins credentials (like missing SecretKey)...
Please refer to log file in .\logs\stdout - this is the quickest way to find details about the problem :)
app.UseDeveloperExceptionPage();
app.UseDatabaseErrorPage();
Those will work after your WebApp fully started, but not while starting the application.
in web.config file change modules="AspNetCoreModuleV2" to modules="AspNetCoreModule"

Thanks to Lukasz for his comments. I was able to see the log and it stated that "ClientId option must be provided". The problem was with the UserSecrets. Since secrets.json is only available in Development, there were no secrets found in Production. Once I had the secrets in my appSettings.json, it worked fine.
Moreover, To replicate this in Local environment, just go to Project properties and change the environment variable ASPNETCORE_ENVIRONMENT to 'Production' and run in local. This will replicate the 500 Internal Server Error in local and you'll get the error message.
Also, ensure that the ASP.NET Core Windows Server Hosting bundle is installed. THis creates a reverse proxy between IIS and the Kestral server.

I would like to add some more info to #Lukasz Makowej answer.
I found out the reason why to have to create the folder, in microsoft documentation it is said that:
stdoutLogFile - Optional string attribute.
".....Any folders provided in the path must exist in order for the module to create the log file...."
So you have to create it yourself :)
Check it out here:
https://learn.microsoft.com/en-us/aspnet/core/host-and-deploy/aspnet-core-module?view=aspnetcore-2.0
I also must said that in my case I had to validate that the web-site had the permissions to access to the "log" folder.
Make sure your web.config is good. I've been stomped more than once by a syntactically good web.config that referred to a module (Rewrite) that wasn't on the server. No error messages anywhere, other than the 500 response error.
Std log wasn't working for me, I had to uninstall all .ENT Core runtime / SDK versions from the server and my local to install the latest one and it worked after publishing everything again from scratch.
Another thing that helped was binding the IIS app to port 5000 without any dns so it actually showed me errors on http://localhost:5000
Encountered this issue yesterday, we also had no logging, no eventlog message whatsoever.
Then we checked the site's authentication settings via the IIS-manager to double-check the settings. And pop suddenly a popup with an error message 'Error on line XXXX'.
Turned out the configuration section was locked in the website's config at server-level.
So try unlocking the relevant IIS configuration settings at server level, as follows:
Open IIS Manager
Select the server in the Connections pane
Open Configuration Editor in the main pane
In the Sections drop down, select the section to unlock, e.g. system.webServer => security => authentication
Click Unlock Attribute in the right pane
Repeat for any other settings which you need to unlock
Restart IIS (optional) - Select the server in the Connections pane, click Restart in the Actions pane
I am attempting to run the default ASP.NET Core Web Application (Web Application Template in VS 2015) via IIS.
I have followed the instructions from the docs here eg setting up a 'No Managed Code' application pool and pointing the Physical Path at the location of the web.config file.
When I attempt to browse to the website root, http://localhost I am getting this error:
HTTP Error 502.3 - Bad Gateway There was a connection error while trying to route the request.
Most likely causes: The CGI application did not return a valid set of
HTTP errors. A server acting as a proxy or gateway was unable to
process the request due to an error in a parent gateway.
The event viewer states:
Failed to start process with commandline 'dotnet ./bin/Debug/netcoreapp1.0/WebApplication2.dll', Error Code = '0x80004005'.
This error shows I have replaced the placeholders
<aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%"
in web.config with the required values
<aspNetCore processPath="dotnet" arguments="./bin/Debug/netcoreapp1.0/WebApplication2.dll"
(update: these placeholders are replaced when you publish)
As per the troubleshooting instructions I have installed .NET Core Windows Server Hosting Bundle and restarted the server.
Running from the command line via dotnet works
Wondering what to try now.
Ok I figured my issue out. I am pointing the physical path in IIS to the unpublished Visual Studio project root directory. This works in previous versions of .net (ie non dotnet core aspnet projects) but doesnt now.
If you really want this to work then you have to publish your app to a temporary folder and copy the Microsoft.AspNetCore.* binaries back into the bin\Debug\ folder along with the refs and runtimes folders
This is a generic error for when IIS can't find the specified .NET Core components ,and doesn't know where to forward requests. In addition to following the official IIS publishing guide, make sure you have:
Installed the correct versions from the download page for latest .NET Core releases
Specified the correct library versions (explicitly or with wildcards) in your project.json
Included a web.config file (preferably using the publish-iis tool), and that the <aspNetCore> key values have been replaced with local values (source, with examples)
I ran into this while setting up a Core 1.0.0 (final) website on a new Windows 2008 Server. Turns out I had mixed up some of the installers from my dev machine with newer versions, and had mismatched library versions (RC2 vs final). Reinstalling the Server Hosting package fixed the problem.
The key to troubleshooting was to get into the console and use the dotnet commands (and resulting error messages) to iterate until I had my site running from the console, since the IIS error page in the browser was useless. I also found some benefit in a few entries in the system Error logs, but not much.
So I have my web.config connection string pointing to my SQL Server on appharbor - from local (running Visual Studios) I can login and the memberships works. However from the build that is on the hosting side I get sorry, an error occurred while processing your request.
This is strange because I made a new user from local and check with SQL Server Management Studio whether or not the data has been added to the hosting server and it WORKS.
From my latest build I get the error:
Sorry, an error occurred while processing your request.
which is weird because they both point to the same server...
Anyone have an idea of what I am doing incorrectly?
ASP.NET MVC project has the "HandleErrorAttribute" on by default. You should remove it from FilterConfig.cs in App_Start Folder to see the actual error rather than the handled response.
It's located in the RegisterGlobalFilters method where filters.Add(new HandleErrorAttribute()); should be removed.
AppHarbor has a FAQ to help you troubleshoot deployment errors like these. In particular, you should inspect the "Errors" interface on AppHarbor and disable customErrors. Please elaborate the question if the FAQ doesn't help you solve the problem.
