Hi,
I've reset windows 10 and had to reinstall Boinc. That went all OK. In Boinc manager I saw all the task that where there before the reinstall so that was looking good. I run also Einstein@home and there's no problem. But Universe@home can't upload/download anymore:

Should I've done something else than just reinstall?

Looking forward for your replies.

I'd suggest exiting BOINC, re-boot your modem, re-boot the PC, then see if the issue is still occurring.

Hi Grant,
thanks for your reply.
Unfortunately it had no positive effect. The issue persists.
I've removed Universe@home and try to add it again, but that did not work.
So now I've reinstalled Boinc and added Universe@home again (that worked) and it is crunching again.
I think somewhere in boinc there was an old entry or so that caused the problem.

Greatings,
karbonade

You were running an expired certificate in an old, retired version of BOINC, likely. The reinstallation picked up current certificates probably. Your logs didn't have enough detail to show for sure. Would have needed http_debug set in the logging options to be sure.

Yes, that makes sense. Well, at the moment everything goes fine. I only lost some WU who where ready, but tat's not a real prolblem.
I'll keep this in mind for whenever something like this happens again.
Thanks for your reply.
