Hi @DarkClown,
no, it's not an individual problem, I have the same issues with the trial universal license. First all applications are unable to connect, but are still working "as a gesture of goodwill", and some days later every application stops working. I signed up for the license via Affinity store.
Things I checked:
Verified my credentials, they work. Wrong credentials cause different errors.
Reviewed my license inside Affinity store to make sure it exists.
Switched off Windows Defender, no difference.
Made sure that there's no other firewall which would restrict. All other installed applications, all other apps on other devices don't have connection issues.
To the Affinity staff: that's the worst kind of publicity you can be responsible for. Your apps are great, but those circumstances with not being able to login and applications stop working completely (!) is a no-go. And the fact that customers are being left with their problem raises fears that it would happen again and again, f.e. when support ends, due to release of V3.
Please take actions to solve this problem as fast as possible.
