safari connection problem El Cap Beta

Hello,


I just installed the Beta 3 of El Capitan 10.11.2. (15c40a) and my SAFARI does not longer work correctly.


If I enter something in the URL bar there is a failure that Safari could not connect to google out of security reasons.

If I enter https://www.google.com directly it works.


Also I have that problem on a lot of websites.


So it might be a problem with SSL. Search at Google:


I switched of the APPLE Time Servers
I deleted and reset the complete Safari - then it works for a few minutes, after icloud synchronisation same problem again

Did SAFARI to fullscreen and back (yes, also that I found on the web for this problem)

.........


Safari does not work correctly. Same problem!


Any ideas from your side? Thanks in advance
