"Could not open file" after updating to V7.2.1

After updating my Nextcloud AIO docker container, I now have issues with external storage, in this case an external drive mounted to the docker container. This is the error I am getting:

`[webdav] Error: Sabre\DAV\Exception\ServiceUnavailable: Could not open file at <>

I have tried all kinds of things (new container, reinstalling docker, creating new Windows user) but nothing seems to help. I made a backup before the update. Anyone who can help me?

I too keep running in to this. I am at a loss as to what to do here. I end up re-building the structure with various occ commands, and things seem to work for a bit, but then stop again. I am running this in unraid, utilizing the docker nextcloud from linuxserver.

I was having preview generation errors, and worked through those by searching but this seems to keep coming back, and I don’t know how to permanently resolve it. I would like to add more users to this testing, but cannot until this is resolved, and I can reliably use nextcloud.

In my installation it seems like the clamav Plugin is causing the issues.
Try to deactivate it and test the upload again.
