Android Permission denied for tunnel

I’ve been unable to get any connection going on Android today.
I keep seeing :

“VPN permission was denied when creating the tunnel. Please try connecting again”

I’ve tried different regions, clearing cache etc., however the issue persists.
Anybost have an idea what could be causing this? Could it be due to an update or something else?

Go to your network settings and make sure Mullvad appears under VPN and if it doesn’t, add it.

Where can I find the example configuration to fill into the fields?
Type, Server address, username, etc…

edit:

Nevermind, after reinstalling the app, removing the entry in the network settings and restarting my phone it started working again.
