Frequent disconnects from VPN

I am seeing this more and more from my connection. This occurs with both Tunnelblick and now I'm using Viscosity

My client automatically reconnects but it will often fail in authentication because airvpn shows me as still logged into a server, so I have to manually log into the airvpn client area page and disconnect there.

Hello!

 

The "No route to host", code 65, may be caused by a line drop or a null-routing of the destination IP address or a firewall in your system that drops packets (for example when it sees "too much" UDP flow).

 

Please see here (about Tunnelblick):

 

http://code.google.com/p/tunnelblick/issues/detail?id=120

 

and here (about SparkLabs Viscosity):

 

http://www.sparklabs.com/forum/viewtopic.php?f=3&t=1227

 

We can't verify the logs on the server side because OpenVPN logs are sent to /dev/null according to our policy.

 

Try to connect to a TCP port to see whether the problem gets solved or not, which may be a precious hint.

 

Kind regards
