[rabbitmq-discuss] .NET ssl_upgrade_failure

Thu Aug 2 15:22:54 BST 2012

Matthias,

stunnel may not be a viable option for our deployment requirements.  I will 
continue to investigate my situation.  I am in the process of setting up 
rabbitmq on a linux box to see if I obtain different results.

I have tested {verify, verify_none} and things turned out a little 
different.  The .NET client continues to give the exception "None of the 
specified endpoints were reachable" but on the server side I see this in 
the log.

=INFO REPORT==== 2-Aug-2012::09:01:08 ===

The Java client continues to connect and transmit fine through the server.

The following is the packet trace of the connection attempt between the 
server and the .net client with verify, verify_none
