Ubuntu connection drop

Recommended Posts

Hi everyone,

 

I was using AirVPN for several month now on Mac OSX with Tunnelblick and it worked flawlessly.

No I have configured it on my Ubuntu laptop, all settings exactly like in the help section and here:

https://airvpn.org/?option=com_kunena&Itemid=55&func=view&catid=3&id=116

 

It works at first, AirVPN.org website tells me I'm connected, but just after a couple of seconds, I only get timeout errors.

I'm using the network-manager under Ubuntu.

 

Any idea?

Thanks

murph

I can access about 4 URL's then, and then it breaks up.

If you need other logs I would be grateful for a hint where those are, I'm new to Ubuntu.

Hello,

 

no apparent problem is showed in the logs. Does the same happen if you connect directly with OpenVPN?

 

Kind regards

Interesting!
When I run it manually as root, it seems to work, no hang up so far:
