CC and LR are suddenly unable to work with

I have been working years with CC-> LR & PS and never occured any problems.

But since this week suddenly when I wanted to start LR it said I needed to make contact with CC but possible there could be problems with the website/server of Adobe. And on the other hand it could be my firewall and/or mac clock.
But my firewall settings or internal clock hasn't changed whatso ever...

When I want to log into CC or even Adobe's website, I fill in my email,... they send me a code to my mobile phone and after that I am respawned at the log-in screen as before.

I tried to uinstall the programm but was unsucceful. LR said it could not be uninstalled because of the connection problem? And CC could not because still there were app attached too.

Atlast I was able to sign in to the website, but every so many seconds a second window opens sayin: I was able to log in to the website.

I am out of ideas...
I tried the autobot chat but... well... auto bot.
