This channel is not responding

Hello everyone,

New to the Plex Pass!

All the channels that i try to add, i Just get the message : "This channel is not responding." for ALL the channels.
None of them works.
Is it again because I'm in Canada?? (yes my regional settings are Canada)

Here's what config info I have to offer:
Windows 10 Pro v.1709
Plex 3.20.7

Thanks for your help!!
