I'm running Ubuntu and using Electrum 1.9.8. When I have my VPN turned on, the Electrum wallet says "synchronizing" for a few minutes, then gives up trying and says, "not connected." I have tried connecting to several servers and even made sure they were online at http://electrum.qc.to/

Anyways, if I turn off the VPN, then Electrum connects and synchronizes immediately.

Any tips on how to get it to work or settings I can check?

Thank you!
