[Openvpn-users] What causes connection reset errors?


  • Subject: [Openvpn-users] What causes connection reset errors?
  • From: Yan Seiner <yan@xxxxxxxxxx>
  • Date: Thu, 08 Nov 2007 18:33:45 -0800

I just shipped out another client and it's failing to connect.  I tested 
it thoroughly before it went out and it worked fine but now the 
connection is getting reset.

Which end is getting reset?  Mine or the remote?

Any clues as to why?

Thanks,

--Yan
