(moderation:
Einstein@Home will be shut down tomorrow (Wednesday Oct 8) morning (CEST) to perform some urgently necessary database work. We expect this to take a couple of hours.

Server seems to be back up (I can post here!), but I'm getting a connection error when I try to report completed tasks.

Yep, the scheduler URL was changed.
Do you happen to know how from the project side we can instruct the clients to read the new URL from the "Master URL" (i.e. index page)?
According to the client code the client should do this automatically after 10 consecutive failures, which may take a while.

Just wait, and let time (and itchy trigger fingers) do the rest.

That was a pretty long day for us. The basic things should be working again. Some minor things (stats export, scheduler log publishing, db purging) don't work yet, but we'll do this after getting some sleep. Tomorrow I may also give a more extensive report on what we actually did.

Perhaps there is a difference depending on whether work is being requested.
Three of my PC's that wanted work seemed to take about 5 update requests each, but my laptop, which was off all night and had work to report but none to request, logged eleven "Scheduler request failed: HTTP file not found" entries before finally doing the "Fetching scheduler list, Master file download succeeded" pair, after which the next update request succeeded.

Computers which were active during the (European day / American night) probably got through their first few attempts during the 'down for maintenance' period, so fewer were needed to reach the "after 10 consecutive failures" trigger that Bernd mentioned. If the machine has been off, you need to do them all yourself.

I had several tasks waiting to be sent back and after a few tries it started to work again and sent and received once again.

Minor problem with thread

Minor problem with thread marking : just on reading a thread it wasn't marked as read, but the "Mark all threads as read" button fixed it.
But now having just tested again via reading, it's fine now. Oh well .... :-)
