Nextcloud desktop app "not responding"

Hi,

Something happened, but I canā€™t find out what. The result is that Iā€™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:

2023-03-15 15:28:19:641 [ warning default qrc:/qml/src/gui/tray/SyncStatus.qml:107 ]: qrc:/qml/src/gui/tray/SyncStatus.qml:107:13: Unable to assign [undefined] to QFont 2023-03-15 15:28:19:642 [ info nextcloud.gui.account.state C:\Users\sysadmin\AppData\Local\Temp\2\windows-14239\client-building\desktop\src\gui\accountstate.cpp:265 ]: check connectivity 2023-03-15 15:28:19:643 [ info nextcloud.sync.credentials.webflow C:\Users\sysadmin\AppData\Local\Temp\2\windows-14239\client-building\desktop\src\gui\creds\webflowcredentials.cpp:139 ]: Fetch from keychain! 2023-03-15 15:28:19:660 [ info nextcloud.gui.socketapi C:\Users\sysadmin\AppData\Local\Temp\2\windows-14239\client-building\desktop\src\gui\socketapi\socketapi.cpp:319 ]: New connection QLocalSocket(0x1e087ae9990) 2023-03-15 15:28:19:661 [ warning nextcloud.sync.credentials.keychainchunk C:\Users\sysadmin\AppData\Local\Temp\2\windows-14239\client-building\desktop\src\libsync\creds\keychainchunk.cpp:360 ]: Unable to read "Nextcloud_[USERNAME]_clientCertificatePEM:https://cloud.k-elf.nl/:0" chunk "0" "Password entry not found" 2023-03-15 15:28:19:662 [ warning nextcloud.sync.credentials.keychainchunk C:\Users\sysadmin\AppData\Local\Temp\2\windows-14239\client-building\desktop\src\libsync\creds\keychainchunk.cpp:360 ]: Unable to read "Nextcloud_[USERNAME]_clientKeyPEM:https://cloud.k-elf.nl/:0" chunk "0" "Password entry not found" 2023-03-15 15:28:19:663 [ warning nextcloud.sync.credentials.webflow C:\Users\sysadmin\AppData\Local\Temp\2\windows-14239\client-building\desktop\src\gui\creds\webflowcredentials.cpp:484 ]: Unable to read client key "Password entry not found" 2023-03-15 15:28:19:664 [ warning nextcloud.sync.credentials.keychainchunk C:\Users\sysadmin\AppData\Local\Temp\2\windows-14239\client-building\desktop\src\libsync\creds\keychainchunk.cpp:360 ]: Unable to read "Nextcloud_[USERNAME]_clientCaCertificatePEM0:https://cloud.k-elf.nl/:0" chunk "0" "Password entry not found" 2023-03-15 15:28:19:664 [ warning nextcloud.sync.credentials.webflow C:\Users\sysadmin\AppData\Local\Temp\2\windows-14239\client-building\desktop\src\gui\creds\webflowcredentials.cpp:525 ]: Unable to read client CA cert slot "0" "Password entry not found" 2023-03-15 15:28:19:665 [ debug nextcloud.sync.account C:\Users\sysadmin\AppData\Local\Temp\2\windows-14239\client-building\desktop\src\libsync\account.cpp:623 ] [ OCC::Account::slotCredentialsFetched ]: User id already fetched.

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 ā€œsyncedā€ 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, Iā€™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 doesnā€™t sync and the Nextcloud Client app stays in ā€œNot respondingā€ 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 ā† this file exists?

Donā€™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 canā€™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 ā€œsync hidden filesā€
re-entre adress and so onā€¦
It works :grinning:

I have the same problem on Win 11 Pro v10.0.22621 Build 22621 with the just updated Nextcloud Win App v 3.8.0. The problem occurs just when the app starts syncing. If I enable the maintenance mode server-side, the app works fine. The same applies when I end the app task, restart it and immediately open the settings thus the main window. All works. As soon as syncing starts, the app freezes. It seems to sync though.

I also suffer under Windows Explorer issues which I did not relate to the nextcloud app so far but as I read the other comments, I notice that the problems came along with the nextcloud issue.

Reading through this thread lead me to solve the issue: Disabling automatic bandwith limiting.

I have similair trouble. My nextcloud is behind a reverse proxy and it is working great with nginx.
But I want to switch to apache due to problems with refreshing Letā€™s Encrypt certificates on nginx.
Apache revprox gives me these problems. I had to completely remove the client and cache and re-install to get it to work more.
But now it is stalling the Windows exporer.exe (not the IE browser) and gets stuck with a connection lost after a while.
