I have an issue with reporting my 100% finished Jobs:
They don't disappear out of the active queue - the log file shows, that
'Project communication failed: attempting access to reference site
Internet access OK - project servers may be temporarily down'

On one of my PCs not running active LHC jobs I removed the project and tried to add it, again:

Result: https://lhcathome.cern.ch/lhcathome/

Adding this project failed - try again later ...

If looking to the project site the server status seems to be OK...

Does anybody has the same behaviour?

Thank you very much in advance!
Claus

I'm not 100% sure but it might be related to the issue caused by an expired CA certificate:

In your BOINC folder you may replace ca-bundle.crt with the most recent version from here:

There is a hotfix available mentioned by BOINC's alpha-tester Richard Haselgrove: https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=5441&postid=42728

Dear computezrmle,

thank you very much! - this helped:
It was the outdated "AddTrust External Root"-certificate, which I just deleted out of the file...
( a description, how to add an actual one is also availble in the thread)
After a restart of BOINC I could add the project, again...
