NordVPN causes connection issue?

I do not have great connections with Jami. I have done tests with my desktop, phone and tablet devices and have made some test accounts and sent messages from A to B, B to A and tried making calls. Sometimes it works, sometimes not.

I think I may know why and this maybe the case for many others. I use a VPN but more specifically I use NordVPN. NordVPN disables port forwarding and UPnP. And this maybe why users are having issues. I am not sure there is a way around this for Jami and I still have to do more tests to confirm that when NordVPN is on, that it is indeed causing connection issues.
