Hi Philip,
Thanks for your answer. I performed the steps you described, but unfortunately its still not working - I'm getting different error messages though, so that's something :)
To recap:
- When the Sandbox is not running, the CrmAsyncService logs says:
System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at net.tcp://myserver-fqdn/CrmSandboxHost that could accept the message.
This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
- When the Sandbox is running without SSL (SandboxEnableSSLSecurity = 0), it says:
System.ServiceModel.ProtocolException: The requested upgrade is not supported by 'net.tcp://myserver-fqdn/CrmSandboxHost'.
This could be due to mismatched bindings (for example security enabled on the client and not on the server).
- When the Sandbox is running with SSL (SandboxEnableSSLSecurity = 1 with the thumbprint and host name configured), it says:
System.ServiceModel.CommunicationException: The socket connection was aborted.
This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:01:00'.
When I look at the stack trace of the last error (see below), it seems that I got a little further, since it contains a call to "System.Net.Security._SslStream.StartWriting", which tells me that it attempts to write something through SSL, right?
So next question is: why is the socket connection being closed?
Also, another thing I noticed:
When I misconfigure the SandboxSSLCertificateThumbprint, the Sandbox service refuses to start (so it actually uses this registry setting).
However, when I misconfigure the SandboxSSLCertificateDNSName it doesn't seem to care, it starts normally, and in the Windows Event Log viewer, I always see it listening to localhost:
The Sandbox Host service has started.
Source: Microsoft.Crm.Sandbox.HostService.exe (12060)
Endpoint: net.tcp://localhost/CrmSandboxHost
The Sandbox Host service has started.
Source: Microsoft.Crm.Sandbox.HostService.exe (12060)
Endpoint: localhost/CDSSandboxHostStatus
The complete stacktrace of the last error is:
