LHC@home

After several CMS tasks had crashed, they were shown in the BOINC Manager with "computation error", and I was not able to remove these tasks from the Manager (however, I could remove them in the Oracle Virtual Box Manager). As long as this was the case, no new tasks could be downloaded; no way to get these entries removed from the BOINC Manager.
So I decided to reset the project, which was successful in a way that the crashed tasks did no longer show up in the BOINC Manager.
However, if I click on "update", the BOINC Manager in the "status" column shows "communication deferred 24 hours, and this is now counting downwards every minute, for the next 24 hours :-( In other words, I will have to wait for a full day in order to get new tasks downloaded.
What's going wrong? Any ideas how to solve the problem ?

Did you try with a restart of the BOINC client?

no, I hadn't done this. So I did it now. Before, the remaining time was about 23 hours and a few minutes. After restarting the BOINC client, the remaining time again jumped to 24 hours and is now counting downwards from there.
So something seems to be awfully wrong :-(

Now the counter showed some 21:58 hours, I closed the Boinc Manager and the Boinc client, and ran a repair Installation of Boinc. Even this did not help: when opening Boinc, the counter jumped back to 24 hours.

BTW, someone in the BOINC forum mentioned that there might be a 24 hours' stop of getting new tasks once a task has been abortet. This though would be totally new to me; I have been aborting tasks sometimes over all the years (for one reason or the other), but there has never been a 24-hours ban for getting new tasks. Does anyone happen to know more about this?

I think all I can do is to completely uninstall and then reinstall BOINC - any other suggestions?

Problem solved: by coincidence, I noticed that the IP address of the notebook was changed (no idea how come, because on the router I have set it as fixed). And for this reason, the squid proxy did not allow the connection to LHC. So I added the new IP address to the hosts list in the squid.config of the proxy, and now it works :-)
