Again this problem returned, the client stop syncing after a short time 
and logs:

2022-08-03 15:43:42:861 [ warning nextcloud.sync.networkjob 
]:	QNetworkReply::HostNotFoundError "Host  not found" QVariant(Invalid)
2022-08-03 15:43:42:861 [ warning nextcloud.sync.credentials.webflow 
]:	QNetworkReply::HostNotFoundError
2022-08-03 15:43:42:861 [ warning nextcloud.sync.credentials.webflow 
]:	"Host  not found"

This is after updating the OS to 12.3-STABLE over the weekend + all 
ports including Qt.
Client 3.5.3
Qt5 qt5-network-5.15.5p165_1

If I do "Settings -> Network -> Use system Proxy" and then back to "No 
Proxy" sync will resume for a short while and then stop again.

My home workstation is very similar to the one @work which I am writing 
this on now, it runs client version 3.4.3 just fine, so does my old 
Thinkpad with client 3.3.5 that is right now on the same internal 
network as my troubled box and syncing fine.

The problem in question have reappeared several times but also 
disappeared without me understanding why, seems to be more frequent on 
larger data sets though.

Anyone else seeing this? Any suggestions where to look?
