Yesterday I upgraded Nextcloud from version 17.0.9 to version 18.0.10. A user reported a synchronization problem with some of his folders.
When he looks at his Nextcloud client he can see all the folders and that they are well synchronized:
But when he looks in his Windows explorer, only one folder appears:
Miscellaneous information:
Folders are present on the web interface
Nextcloud client version is 3.0.2.15836
All conflicts have been resolved, the nextcloud icon is now green
The folder is in a folder created by the plugin “Group Folder”.
No error message in server logs
The problem is only present on one computer at the moment
The synchronization logs do return the information that the folders are downloaded, for example:

I would like to know some information:
How to identify the problem on Nextcloud clients to see if other folders are not synchronized?
most likely you have to re-sync the folder. Try uncheck and check this folder again.
I think the only way to find out if there are missing folders is to compare directories on NC (e.g. by using WebDAV mount) with the local directory. Some file managers like Total Commander have built-in directory compare/sync tool. By default it seems to be no persistent client log. but you can review the client log by pressing F12 - here you have select the option to persist the client log as well - but I’m not aware if this setting is persistent across reboots.
Maybe reviewing the log after triggering a re-sync gives you a hint…
Keep an eye on that, I don’t trust the client version 3. When I upgraded the client to 3, it lost four out of five syncs, and the last remaining one didn’t work properly. Even after I removed the remaining sync and recreated them all, folders were intermittently not syncing individual files between my desktop and laptop.
I gave up and uninstalled client version 3, and reinstalled 2.6.5. Everything has worked fine since then. I figure I’m gonna wait until 3.1 is released before trying it again.
