InDesign (16.4) stopped working overnight

[Peter1345]

Hello

My InDesign version 16.4 has the following messages: Your subscription status cannot be confirmed. However, this cannot be correct, the subscription is correct.

Then follows: An error has occurred, are you connected to the Internet? - Yes, I am.

After restarting the computer, the entire InDesign no longer reacts. A downgrade to 16.3.2 does not work either.

What's the problem here? Yesterday everything went perfectly and the next day nothing works.

Thanks for the answers
