Adobe Creative Cloud and InDesign can't reach server, internet works, Illustrator works fine as well

I need help!

Since today InDesign and Creative Cloud refuse to connect to the server, Illustrator works fine though. It doesn't matter what Wifi connection I use, they both won't work.

I cannot deinstall them, as they need a connection to the servers and of course that ain't working.

Also, they both cannot reach/connect any licensing? I don't understand why they both won't work but Illustrator is fine.

I know those screenshots are in German, but the first one says: Your subscribtion cannot be confirmed. (I can log into the website, Illustrator still works, I don't know why... and no, the tips from Adobe's helpdesk don't work. None of them.)

Second screenshot reads: Adobe-Server cannot be reached.

Yet, Internet works. I am currently accessing this website through the exact same wifi-connection I would use for the programs.

If anyone knows any solutions, I would be forever grateful. I use these two programs daily for my side business. Also, I am, obviously, a computer noob, so don't be too harsh!

Thank you!
