HI Werner,
For me it did not go away even after infinite page refreshes. I wiped out the installation and did everything again and it went away. No clue why it happened. But it said some error in the log which I have posted I guess. But I am sure the following three things could be the culprit.
1. Configuring correct names for client and master in certificate aspect
2. I guess it uses the secure connection to DB also, need to configure that properly
3. Master should be running correct date and time...
Thanks
Raj
