Protonvpn connection failed due to unknown reason

Trying to connect to ProtonVPN either manually or via ‘protonvpn-cli c’ results in a failure:

Setting up ProtonVPN.
Connecting to ProtonVPN on US-FREE#2 with UDP.

Unable to connect to ProtonVPN: ProtonVPN connection failed due to unknown reason.

Changing from server or from UDP to TCP doesn’t do anything. Any help is appreciated.

Check the logs it should say why
