Can't connect to servers on Ubuntu

[karlschmidt 0]

I've been using the Airvpn client on this installation of Ubuntu 14.04 for the past few weeks without any issues. This morning, after I booted my computer, airvpn would connect to one server, stay connected but no websites would load. I tried connecting to several servers in other countries and it didn't even connect. I uninstalled the airvpn client, and then installed the new version, no luck it doesn't connect to any server. It gets stuck at "Checking route" for a minute then disconnects and tries again. As a test, I downloaded the Mullvad client and tried it, it would connect to a server but websites wouldn't load. Really not sure what the issue might be as I didn't install or uninstall any new software last night, and my wifi is working fine, any idea what it might be and how I could fix it?

 

Thanks in advance for your help
