problem loading some pages completely - ubuntu

[jorfin 0]

Hi,

I've got a weird problem that I can't seem to solve:

I'm running Ubuntu Gnome 15.10.

I have installed the airvpn client from the .deb package and its running normally.

But many websites won't load completely. for example facebook just loads most of the page elements but won't load the feed if i scroll down. other pages have similar problems or sometimes won't load at all.

As soon as I disconnect, everything runs smoothly again. It happens with every server location, every browser I have tried and every kind of dns sever setting.

I also tried it on ubuntu 14.04 just to make sure. same thing again. (I've been using airvpn on windows for a long time without problems)

I disabled the firewall and my ubuntu is a fresh install.

 

Maybe I'm missing something here, but I can't figure out what to do.

 

Any help would be appreciated
