Is this the first time you’ve seen this error? (Yes / No): No

Are you using Cloudflare, mod_security, or similar? (Yes / No) No

Summary of the issue you are facing:
On Windows 11, when updating windows desktop client 4.0.X to 33.X some folders become unavailable with error message “Location is not available C:\users\XXX\Nextcloud is not accessible. The cloud operation was unsuccessful.”
I have to roll back to version 4.0.X to restore access to more folders, but usually need to restore previous configuration file and/or reset synchronization database to have access to (nearly) all folders (I still have a folder unavailable, “Documents” in the following logs).
Folders are available when accessed on web server . I have a virtual desktop with windows client 4.0.8 which can access all folders (I never upgrade it to 33.X).
I tried to install desktop client 33.X on another laptop, just to be sure the problem was not my laptop profile. On this one, it is the folder C:\users\XXX\Nextcloud which is not available, so I can’t access any folder.

Thank you for your help. I tried every new release since 33.0.0, hoping I won’t have the problem. Perhaps I missed a prerequisite.

Regards.

It is a critical error, one time you have “Nextcloud” the other time “NextCloud” in the path! Not sure where the difference comes from, if one is the actual filesystem and the other in a config file…?

Hello tflidd,

Thank you for your answer, you were right, the typo was in the configuration file I restored after the error. Unfortunately, correcting this typo did not solve the problem; the error message is still present, with “Nextcloud” spelled correctly this time.

Seems like the 33.X version changed some folder security settings, I am unable to delete the problematic folders. I tried with an admin user, Nextcloud client closed, and after uninstalling the client. Even the deletion of the Windows profile is not fully working, I still have the C:\Users\xxx\Nextcloud\" in the old profile (and only these ones).

Hello,

Seems like I am the only one having issues with the 33.X version.

I will be on holidays next week, but if someone has an idea, I will be happy to test it when I come back !

5

Do you have this problem on other client systems as well? With a different user as well?

If no one else has the problem, I’d look what is a bit special in my system, what kind of software, some extra features/apps/plugins/…

6

This is interesting. The casing is different here. The error itself is saying that the former is not within the latter, which is technically true.

Thanks for the highlighting. Based on this finding, What should be the solution to fix this issue.

Hello,

I come with some news.

@tflidd yes I have the same problem on others laptops and with different users.

I tried installing version 33.0.7, seems like I have access to all folders (except my former “Documents” folder, but I think it will be lost forever on my laptop), but I have a lot of “Couldn’t update placeholder info” on files in severals subfolders, and I can’t open these files.

If I come back to 4.0.11 i don’t have any file or folder problem.

I don’t know what changed with windows clients 33.X, but my laptops doesn’t like it. I just hope that it is not one of the programs I need to stop to uninstall Nextcloud (Outlook, firefox, zoom, …) that is causing this problem…
