Fix sync issues #5615

Closed benjaoming closed 4 years ago

benjaoming commented 4 years ago

Summary

Very slow syncs (>2 minutes) were taking place on the staging Central Server and mostly timing out (Cloudflare timeouts!).

This caused IOErrors on the server's UWSGI.

A few error handling incidents were also encountered and errors should be more readable now.
