Well after spending 24 hours asking for work and not getting a single workunit I decided to experiment.

I have my primary profile set to a resource share of 0 so that I can disable projects remotely just be changing the location of each host. Normally, the hosts run under location "school" with a resource share of 1000.

I noticed previously that when asking for work, the GPU had an apparent share of 0.00 so I changed the primary setting to have a resource share of 1000, set the default location to "---" (the primary one), removed the project then added it back and now the error messages are listing the share as 0.50 (I'm also running Moo with a resource share of 1000) ... and I'm getting work!

It would appear that for some reason the preferences no longer get updated when using profiles other than the primary one.

Tried attaching to the project again after a spell away - can't get any work.
The host has ran Collatz in the past and is quite happily running Moo now so I know the GPU works.

Host is - https://boinc.thesonntags.com/collatz/show_host_detail.php?hostid=811276

Detached the project.
Installed VC++ 2017
Re-attached using the "http://" link, (got a message in the logs - "This project is using an old URL. When convenient, remove the project, then add https://boinc.thesonntags.com/collatz/"!)
Requesting work but not getting any.

Interestingly, the work_fetch says "16/05/2018 21:37:09 | collatz | [work_fetch] REC 0.000 prio -0.000 can't request work: scheduler RPC backoff (115.99 sec)" but doesn't give a reason why.
The backoff counts down to zero with each fetch then resets to 600 and starts counting down again.
I don't have the "Use CPU" box ticked in preferences so I can understand why I'm not getting any CPU tasks but no idea why there's no Nvidia tasks downloading.
Also I don't understand why the work_fetch share is 0.00 for the GPU as it's set to 1000 in my preferences here?

As posted by mmonnin in a different thread, a snapshot of the forums upto last october is available here - https://web.archive.org/web/20171012015502/https://boinc.thesonntags.com/collatz/forum_index.php

Doesn't help with the LOTPW information (episode 27 was still running) but the older information is still available for the OP.
