Adobe Connection Manager unable to connect to Adobe Servers

Hello,

I have found many threads for that topic, but non helped me solve my issue.

I haven't been using my application in quite a few months. A few weeks ago I started again and always get the message that my membership could not be verified because it cannot connect to the Adobe Servers. I started the Application Manager and get the same message there.

I tried everything in this document: http://helpx.adobe.com/x-productkb/policy-pricing/activation-network-issues.html and all steps are successful

I tried to connect my laptop directly with the LAN cable to the modem, still no success

I don't use any Proxies.

I disabled my firewall and Antivirus, Spyware, etc. applications, still it says it cannot connect.

I tried to download the Desktop Application, but also get the message it cannot connect to the servers.

I really do not know what to check anymore. I have no problems with secure sites or anything else I am using.

Any suggestions what else could be the problem?

Side note: It says to set the clock correctly. What time yone does it check against? My Windows is German, he CC is German, I am in Germany and use the correct timezone. I often use the US formatting of numbers and date formats, because I need it hat way for work. I tried it with both US and German settings, though. Makes no difference.

Thank you!
