[stunnel-users] Peer suddenly disconnected

[Mark Tabash]

Hello,

I'm having problems using stunnel. I would be glad to provide further 
information upon request. The funny thing is that it was working before 
I shipped the client pc to the remote location. Nothing has changed since.

Here's what I get in the logs:
