Investigate why config requests take so long to complete

[Saxon Milton]

It was found that a 10 → 20 second modification of the netsender http client timeout was required to get the config requests to work without exceeded the timeout. This seems weird given that 10 seconds should already be enough especially with a good connection speed. We should investigate why config requests take so long to complete and if there’s anything we can do about it.

No longer reproducible.

Possibly due to VidGrind being overloaded at the time, due to being constrained to run a single instance, which is no longer the case.
