I am currently hosting my redis cache server on Azure, and have signalR relying on it as the backbone using the following...
GlobalHost.DependencyResolver.UseRedis("Server",port,"password","eventKey");
This works find on port 6379 (non-SSL) but my chat app breaks when I try to connect to the SSL port (6380) of my Azure Redis server, and the hub is never started. What could be the cause of this issue? Or am I doing something wrong?
This is the error that appears on /signalr/connect in my browser
net::ERR_CONNECTION_RESET
You can try this:
GlobalHost.DependencyResolver.UseRedis(new RedisScaleoutConfiguration(connectionString, "YourServer"));
And connection string something like:
connectionString="yourNameHere.cache.windows.net,ssl=true,password=YourPasswordKey"
Make sure you are using SignalR built with StackExchange.Redis (latest is gratest ;)
I upgraded the signalr core library to version 2.2.3.0 and used the below syntax, works like a charm.
var redisServer = ConfigurationManager.AppSettings[Constants.RedisServer].ToString();
var redisServerPassword = ConfigurationManager.AppSettings[Constants.RedisServerPassword].ToString();
var connectionString = $"{redisServer},password={redisServerPassword},ssl=True,abortConnect=False";
GlobalHost.DependencyResolver.UseRedis(new RedisScaleoutConfiguration(connectionString, "APIIdentifierString"));
In case anyone else hits the issue, it seems that the default connection string provided by the Azure portal contains abortConnect=False.
Once I've removed that part, things started working for me.

I have integrated paypal to my MVC4 application. PayPal dll version 1.5.0.0, NewtonJson dll version 6.0.0.0
At first i got exception at localhost while getting access token
Dictionary<string, string> sdkConfig = new Dictionary<string, string>();
sdkConfig.Add("mode", "sandbox");
string accessToken = new PayPal.Api.OAuthTokenCredential("MyClientId", "MySecretId", sdkConfig).GetAccessToken();
Exception was
Invalid HTTP response: The request was aborted: Could not create SSL/TLS secure channel.
From stackoverflow I got a fix
System.Net.ServicePointManager.Expect100Continue = true;
System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;
System.Net.ServicePointManager.DefaultConnectionLimit = 9999;
Its currently working fine on my localhost, but getting exception when uploaded and run on AWS windows instance.
Retried 3 times.... Exception in PayPal.HttpConnection.Execute(). Check log for more details.
Can somebody help me on this ?
UPDATE
I have checked with uploading the same code in mochahost server. Its working perfectly there too
My EC2 instance is Windows Server 2008 DataCenter, 32 bit with IIS7
Make sure TCP443 is open on any elastic load balancer (ELB) you are using and in the security group assigned to the EC2 instance. In the OS make sure TCP443 is allowed with Windows Advanced Firewall.
I am prototyping a message queue solution developed using CodeIgniter. The code is hosted on a GoDaddy basic shared hosting plan and connects to a trial instance of RabbitMQ on CloudAMQP. I use the videlalvaro/php-amqplib library.
The solution worked fine for a few days and yesterday I started getting a connection refused error. No changes to the code, in fact the same code running on my local machine works fine and connects to CloudAMQP.
This leads me to believe that the problem could be with GoDaddy hosting. Have spent about 48 hours trying to work around this and my project is now stalled.
Does anyone have any ideas? My only option now is to move to a different hosting service and try but that's a major step and I wanted to be sure I'm not missing something small.
The relevant part of the code below:
$url = parse_url("amqp://yyyyyyyy:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx#moose.rmq.cloudamqp.com/yyyyyyyy");
//Masking the user name and password for here
$conn = new AMQPStreamConnection(
$url['host'], //host - CloudAMQP_URL
5672, //port - port number of the service, 5672 is the default
$url['user'], //user - username to connect to server
$url['pass'], //password - password to connect to the server
substr($url['path'], 1) //vhost
);
For those who may face a similar problem, this could have been because of hosting on GoDaddy (could apply to any hosting service) where presumably access to post 5672 is not allowed. I moved to AWS and everything is working fine.
This question can be closed (not sure how that happens).
Thank you zaq178miami, your inputs helped.
I have dowloaded latest version of genymotion with proxy server 2.2.2 and while connecting i am getting invalid reply from server (do you use a proxy?). I am not using proxy for sure. Any ideas?
Answer, its all about the http proxy server on the genymotion settings just UNCHECK on the genymotion setting or remover the http proxy server by UN-ticking the ability to enter HTTP PROXY and PORT let it be blank by unckecking hence login your credentials, if it doesn't work try confirming you email with genymotion.
In my case I went to Settings > Network > I checked "Use HTTP Proxy" and I filled the Http Proxy and port fields (with company proxy valid values).
After that I connect smoothly as silk.
I had the same problem in ubuntu and after some struggle when i was almost giving up i stop the docker (had one instance running in port 3337 in my PC) and for my surprise it's finally work.
I had a similar issue (invalid reply from server without Proxy, on a highly customized and quite broken ubuntu 16.04). nothing of the above helped. (seemingly)
Then I visited this site:
http://qaru.site/questions/835901/genymotion-stuck-on-splash-screen
(well, you have to let google translate it, if you are not russian)
the error described there is completely different. (computer crash resulting in different networking issues)
but it had one thing in common with my case:
everything worked fine, and then suddenly: SOME NETWORKING ERROR - without reason
well, for me, the solution was the same as described on the russian page:
removing a (corrupted?!) conf file.
the conf file was at (my home folder)/.config/Genymobile/Genymotion.conf
i deleted it (i had to do it with root, because the file was owned by root, but this might have been the case because i messed a bit with genymotion...)
Then, i restarted genymotion and logged in again and it worked like a charm.
I had to allow Genymtion.exe in windows firewall. I'm using v3
Had the same problem, managed it using a VPN.
I'm using glassfish 3.1.1 with an application client container called via java web start.
My program is not working , it remain glued in the lookup() and never pass it .
Context c = new InitialContext()
geo = (GeoBeanRemote) c.lookup("java:global/server_side/server-ejb/GeoBean");
System.out.println("end lookup");
I have already tested this in a windows server and it worked perfelcty but now , in the production server (ubuntu 11.04) it doesn't .
How can i fix this ?
Thanks.
It sounds like you might be having some routing issues. I suggest verifying your RMI port is open. The default is 3700.
I'm doing my dev work on a Window 7 x64 machine, deploying to a Windows 2008 x32 server. At the moment I'm adding WCF services to some internal apps so that we can build smaller clients using net.tcp bindings that report to the user what the server is doing without running multiple instances of the server. To cut back on how much administration the apps will require, I tried enabling port sharing on my first server app. I'm using the app to self-host the WCF service so they can be easily moved from one server to another if necessary. Here's the code starting the server:
Dim _service_host As ServiceHost
Dim active_server_address As Uri = New UriBuilder("net.tcp", "localhost", CInt(My.Settings.ServerPort)).Uri
_service_host = New ServiceHost(GetType(UpdateServiceOps), active_server_address)
_service_host.AddServiceEndpoint(GetType(IUpdateService), New NetTcpBinding With {.Name = "endpoint_tcp"}, "MiddlewareEndpoint")
_service_host.Description.Behaviors.Add(New ServiceMetadataBehavior)
_service_host.AddServiceEndpoint(GetType(IMetadataExchange), MetadataExchangeBindings.CreateMexTcpBinding, "mex")
_service_host.Open()
That works great. When I change it to what's below, however, I get an error. Here's the code:
Dim _service_host As ServiceHost
Dim active_server_address As Uri = New UriBuilder("net.tcp", "localhost", CInt(My.Settings.ServerPort)).Uri
_service_host = New ServiceHost(GetType(UpdateServiceOps), active_server_address)
_service_host.AddServiceEndpoint(GetType(IUpdateService), New NetTcpBinding With {.Name = "endpoint_tcp", .PortSharingEnabled = True}, "MiddlewareEndpoint")
_service_host.Description.Behaviors.Add(New ServiceMetadataBehavior)
_service_host.AddServiceEndpoint(GetType(IMetadataExchange), MetadataExchangeBindings.CreateMexTcpBinding, "mex")
_service_host.Open()
I get the following error when I put a breakpoint at the last line: Unable to automatically step into the server. Connecting to the server machine 'nettcpportsharing' failed. The requested name is valid, but no data of the requested type was found. The Try...Catch block housing that code says the exception type is AddressAlreadyInUseException...but when I run netstat I don't see anything else listening on that address. There's no occurrence of 'nettcpportsharing' anywhere in my solution. I've checked to make sure that the Net.Tcp Port Sharing service is started. Any ideas?
I think this may be a permissions issue. Please see the associated article which explains how to configure the port sharing service to support self-hosted services.
(For production purposes I would strongly recommend using IIS Hosting with WAS anyway - it makes management of the services much cleaner and you get dynamic startup/shutdown for free.)
