tunnel connection 502

[jean]

 I did some packet captures and you can see the session establish, it sends what i assume is an authentication code, and it terminates the session with a fin.  After that it tries to send more data and it sends a a reset back because the port isn't open anymore.  Looks like the session starts and the server closes the session. Gives a tunnel connection fail 502 response.  When I resolve mymidnite from one ISP I get 184.168.131.241 from another I get 159.204.65.201.

I am at a loss of why the session is failing?

any help would be greatly appreciated.
