I'm currently having in my LAN an IIS server that I used to access with my browser by it IP (HTTP requests), and now I want to config it so I will be able to access it using https instead.
I created a self-signed certificate (in IIS manager) and I added a new binding pointing to the https address, then I exported the cer and installed it on my computer.
But when I tried to access it using my browser ("~https://192.168.0.213"), it pops up an "unsafe" message and then showed this screen:
What should I do in order to solve this problem?
Thanks.

I'm attempting to move to a new server. The new server is Windows 2022 with IIS 10. I've added my domain, lets use example.com, and added a trusted ssl certificate to it. The site is reachable and only accepts secure connections. I pinged the domain and the ip matches the server.
This is the certificate information when you visit the webpage.
My publish settings are set to that domain for all applications that I'm publishing on this server:
https://example.com:8172/MsDeploy.axd
When I go to publish though, it's giving me a message about an invalid certificate.
It's not seeing the certificate that I have for for mydomain.com. Does WebDeploy use a different certificate when publishing? I thought it would use the domain that I'm connecting to domain.
Anyone have any suggestions?
I'm trying to create a new certificate for my website which is hosted on Windows server 2012.
Currently, I have a self signed expired certificate. I would like to try Let's Encrypt SSL cert. So, I've downloaded latest version of Lets Encrypt from https://github.com/PKISharp/win-acme/releases and ran wacs.exe from unzipped folder.
When I select N=Create new certificate and entered my domain, I'm getting below error.
Expected: Certificate installed
Actual: Authorization failed error
It looks like the server is not reachable from the Internet. Your server must be accessible from Internet in order to allow Let's Encrypt systems to verify the ownership of the domain.
According to the error which appears (NXDOMAIN), it may be that the website is too new (DNS registers can take up to 48 hours to replicate), the DNS are not properly configured to point to your server, or maybe you have a firewall or filter which disallows external connections.
Make sure that you can reach your domain from Internet first and it points to your server, then try again to request a certificate.
My Azure VM (Win 2008 R2 Datacenter) runs IIS 7.5 and hosts a half-dozen Web sites. I obtained and installed a certificate to enable SSL on one site. I tested the certificate with the downloaded SSL Diagnostics tool, and all appears great. The tool sent a sample SSL handshake with perfect results (diagnostic info along with the contents of the tiny test web page).
However, the web page is unobtainable using https://... from a browser on either the server or client. Localhost:443 or the server IP address:443 in a browser on the server also fails. No error messages are received, the browser just waits and waits.
What could it be?
If I use a browser on the server and input https://ip address without 443, I get this error in the browser: ERR_CERT_COMMON_NAME_INVALID. "Your connection is not private. Attackers might be trying to steal your information..." and it shows the info from the certificate, like the issuer etc. What's the deal?
Ugh. I needed to open port 443 in the Azure Portal, in my Network Security Group. Another question on StackOverflow steered me to that solution!
I'm trying to test my website locally using SSL with IIS Express. It has the following properties set:
SSL Enabled set to 'true'
SSL URL is set https://localhost:44354/
But whenever I open the https address, I get the following error:
In "Microsoft Edge":
In Google Chrome:
I've read article after articles, including some on SO but to no avail. I've tried the following:
I've deleted my IIS Express Development Certificate
I've repaired IIS Express 10 via the Control Panel
I've removed the localhost certificate I had created manually.
I've added <binding protocol="https" bindingInformation="*:44354:localhost" /> to the bindings section the applicationhost.config
I've stopped and restarted IIS Express.
Some suggest to change the port to 443 but my SSL URL is read-only in .NET IDE.
Some articles I've read:
Running IIS Express without Administrative Privileges
How do I fix a missing IIS Express SSL Certificate?
IIS Express — Getting SSL to Work
and many more...
Any help would be greatly appreciated.
Thanks.
I finally figured it out by following this article How to trust the IIS Express Self-Signed Certificate but a few additional steps:
Export IIS Express Development certificate to a local from. This certificate can be found in the Server Certificates section in IIS 10.0.
Open the Certificate console by calling mmc.exe certmgr.msc from File|Run.
Delete all instances of localhost under the Trusted Root Certification Authorities|Certificates.
Import the newly created certificate. You will get prompted with the following:
Once imported, I went back to Asp.Net MVC 5 project, recompile it and ran it. When I ran it, I got prompted with the following:
This is when I knew I was on the right track as this was the first time I had ever seen this prompt! Click Yes, and now this prompt appears:
And click Yes on this prompt as well. Your project will then launch the relevant browser.
Go to the https address defined in your .net project, in my instance, https://localhost:44354/, and you will now see the padlock displayed in the address bar to indicate that it is a secure site:
Most of these answers were already available in different answers provided on SO but the points that were missing or that I missed were that I had to export my IIS Express Development certificate, delete all localhost entries (which I had done) and then re-import this certificate. Once done, .NET detects the change and you get prompted accordingly.
Anyway, I hope this will help others.
Self signed certificates need to be trusted or browsers won't accept them. You can easily use Jexus Manager to configure that,
https://www.jexusmanager.com/en/latest/tutorials/self-signed.html#to-trust-self-signed-certificate
While if you prefer manually, you can import the certificates to the Trusted Root Certificate Authority store in Windows.
Learn more about SSL, certificates, stores and so on (Google each of them and learn them thoroughly), so that next time you really understand what is the culprit before trying so many irrelevant things.
Jexus Manager also has an SSLDiag feature to identify potential issues,
https://www.jexusmanager.com/en/latest/tutorials/ssl-diagnostics.html
But you need to know enough so as to interpret its output correctly.
I am working on Windows Server 2003 (IIS6), which has two asp.net sites running in seperate app pools. One of the sites has an ssl certificate installed and was running fine on https. The other site has no certificate and does not require https
The problem I have is that when I publish my app from vs2005 to the site with ssl the https urls stop working and I can only use http. The error I get is as follows
From Google Chrome: Error 104 (net::ERR_CONNECTION_FAILED): The attempt to connect to the server failed.
From IE7: Internet explorer cannot display the web page, could be unavailable, dns is not reachable etc
The strange thing is the first time this happened, https eventually became available but I don't know what triggered the availability but when I published an updated assembly to the bin folder of the site which does not require https, the OTHER site became unavailable on https again
Help much appreciated!
UPDATED: Thanks for the suggestions but it turns out that the firewall was not open on the ssl port
Check if the firewall port for SSL (443) wasn't accidentally closed 443. ;-)
If both webs use the same IP address, make sure, that only the web with the certificate uses the SSL port 443 (first property page). The input field should be empty for the insecure site.
If that is not the problem, you could try to debug stopping the web without certificate and restart the web server.
