QField Sync not downloading Projects

[Churros396]

Currently I am having an issue that seems the same as the one discussed below.

• across several projects the syncing to the mobile devices is failing as network error, after going up to 100%
• message logs state: [HTTP/500]
• mirrored by failed jobs on the qfield cloud, stopping after downloading the files
• despite stable network and sufficient cloud storage
• tested across several devices

Discussed in #3592

Hello,
I have several cloud projects I've been working on from my desktop, I keep them synchronized with a mobile device via Qfieldsync daily as I edit them constantly, they consist of sets of vector layers and two raster files I use as offline base maps. Qfieldsync was working just fine yesterday, but ever since this morning it won't sync my projects on the mobile device, "network error" and "[QF/unknown_error] QFieldCloud Unknown Error" keep popping up when trying to download them on QField.

I've tried deleting some files like the heavy raster ones in case they are somehow corrupting the project, even attempted to create a new cloud project with very few light layers but nothing has worked out so far. Could it be a server issue?
