OpenTok CreateSession “Error with request submission”

问题

Since 31th July 2018 it doesnt work.

When I tried to create a new session id, the exception return below error:

"Error with request submission".

var Session = OpenTok.CreateSession(mediaMode: MediaMode.ROUTED);

I've tried this link as the web developer site indicates, and everything is ok. https://support.tokbox.com/hc/en-us/articles/360000046059-Desupporting-TLS-1-0

I'm using .net 4.5.2 and opentok api Version=2.4.6431.26897

Any idea?

Thanks a lot

TokBox Developer Evangelist here.

We disabled support for TLS 1.0 on August 1st which is what your issue looks like. Please confirm that you're not using TLS 1.0 on your production environment.

You can also force TLS1.2 by adding the following:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12

Resolved:

I put this in global.asax Application_Start.

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12

Manik is right. CreateSession fails at app start. You must configure your app to use only TLS 1.2. As of 6/6/19 the OpenTok .NET samples are broken unless you make this change.

OpenTok /.NET samples https://github.com/opentok/Opentok-.NET-SDK

add to OpenTokService.cs:

System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12

Example: Create a demo account. make changes to the app.config for your API_KEY and API_SECRET HelloWorld sample project will fail (at startup) with "System.Net.Sockets.SocketException: 'An existing connection was forcibly closed by the remote host'" deep in the CreateSession Call. in CreateSession -> Post -> DoRequest -> SendData ->SetRequestStream and then about 22 more stack levels down.
