Here's the issue from the log. I presume this is a server side error?

There are no signs of irregularities on the server side, in particular no client download errors accumulating around particular data files.
OTOH all your Gravitational Wave tasks seem to error out, reporting checksum errors on various files, while the Gamma-Ray tasks download an run successful. There are many possible reasons for that - GW data files are larger and may be downloaded from a different location - Gamma-Ray are always downloaded from AEI, Germany, while GW tasks could be downloaded from LA, Milwaukee, NY or Germany, depending on your location (actually: timezone). The could be local virus scanners, firewalls, location filters etc. involved that block or delay download or the client's access to the data.
You could try to set your computer to a different timezone (e.g. UTC+2, Germany) and restart the BOINC Client to get a different mirror, but I'm not sure that this would solve the problem.

Guess I spoke too soon. Downloads are failing again for me.
From the log, it looks like this is the location BOINC is trying to download from.
