Your connection log seems to be fine. The only issue is when the client cannot check the route, but that is not critical.

Can you post your ifconfig and routing table? (ifconfig and route -n commands)

 

Also, if you can run OpenVPN from the command line and see if that helps - will make it more clear if this is a client or ISP

issue. Arch is not officially supported, but since it's the favorite distro of many members here, including me, you can probably

get help if we can narrow down your issue.

I noticed the same. Eventually the client does connect after several tries. Maybe the timeout is too short? BTW, also on Arch with the mono client.

I found a workaround disabling the option "check if the tunnel uses AirVPN DNS".

But i have to wait 5 to 20 seconds before having a working connection after being connected to the server.

So, i think that there is something which block the connection to the DNS, and cause the timeout when the AirVPN client is trying to know if the connection is working.

Maybe it can help devs to post a fix.
