Nextcloud desktop app "not responding"

Hi,

Something happened, but I can’t find out what. The result is that I’m stuck with a non-responding Nextcloud Desktop app and at the same time having trouble with opening Windows file Explorer.

The details of my installation:

Windows 10 Pro | version 22H2 | Build 19045.2604 | Dutch

Nextcloud | File version 3.7.4.45221 | Product version 3.7.4.20230309 | installed on Mar. 9th 2023

Nextcloud server | 25.0.4.1 | See https://scan.nextcloud.com/results/1785afe7-7a10-4d8e-a737-29b475a49294

Observations:

After starting my Windows PC the tray icon for Nextcloud keeps showing Syncing Status
Opening file explorer by clicking on its icon is not working unless I kill the Nextcloud process with the Task Manager.

Deeper dive:

Running Get-Content %APPDATA%\Nextcloud\Documents_sync.log -Waitin PowerShell and then restarting Nextcloud App gives some indication:

#=#=#=# Syncrun started 2023-03-15T14:15:22Z
#=#=#=#=# Propagation starts 2023-03-15T14:15:24Z (last step: 1857 msec, total: 1857 msec)

After this nothing happens and no other sync logs are made.

Looking at nextcloud.log I see following remarkable log-lines:

Further, in the log-file I see a lot of lines like:

2023-03-15 15:28:22:447 [ warning default C:\Users\sysadmin\AppData\Local\Temp\2\windows-14239\client-building\desktop\src\csync\csync_exclude.cpp:445 ]: System exclude list file could not be read: "C:/Users/[USER]/Documents/[FURTHER_PATH]/.sync-exclude.lst"

Little step forward : got a Green Synced status icon for a moment. This was probably because I “synced” a folder manually by comparing files in explorer with files on my nextcloud web interface. Maybe I have to do this manually for every file missing. When done, I’ll post an update.

Any ideas on how to investigate the cause?

Solved: downgraded to Deskytop Client 3.6.6

Too bad ! It is NOT solved. My windows 10 Pro PC doesn’t sync and the Nextcloud Client app stays in “Not responding” status. Does anybody have an idea how to further investigate?

You already have the logfiles, perhaps create a bug report and ask the developers.

C:/Users/[USER]/Documents/[FURTHER_PATH]/.sync-exclude.lst ← this file exists?

Don’t do this, it messes everything up. The client keeps track what it uploaded and downloaded. If you add stuff in the back, that just adds confusion. It can’t compare files between server and client based on size and checksums if they are identical, everything must be downloaded.

Same pb on Ubuntu 22.04 and Nextcloud client 3.7.3 - ubuntu 5.15.0-69-generic
non responsive Nextcloud process stopped ;
.config file Nextcloud trashed ;
restart computer (sorry old mac user habit)
check parameters -unable to uncheck “sync hidden files”
re-entre adress and so on…
It works :grinning:
