Can't reach Adobe-Server Adobe CC

Hey there,

I got a problem getting my Adobe Creative Cloud to work.

After installing the package and after starting the Adobe Creative Cloud I get this Message:

Can not reach Adobe-Server... check your firewall .... and so on...

The System is Windows 10 (18xx)

We are working with a whitelist and every needed adress should be in there.

Here is a Part of the Logfile which , i think, should be the problem:
