root directory unvailable, if external storage is offline on 14.0.1

[ManOki]

Steps to reproduce

1. Update to NC 14.0.1
2. Setup External Storage, e.g. SMB share on NAS
3. Shutdown NAS
4. Login into nextcloud

Expected behaviour

See all my files. In NC13, I got a hint, if external storage was offline, but still able to see regular nextcloud files.

Actual behaviour

I'm getting the error "This directory is unavailable, please check the logs or contact the administrator"

From my point of view, this is closely connected to #11442.

My guess: there is no problem with my normal nextcloud data. If my external storage is offline, i get the following error. in latest NC13, there was just a hint, that external storage is atm not available, but i was able to see all other files. now, exception handling seems to be changed and this exception is threated as an error, not a warning/info anymore.

[nextcloud-bot]

GitMate.io thinks possibly related issues are #11442 (root directory unvailable to some users on 14.0.1), #3789 (External storage), #4730 (Storage), #11361 (Increase version for 14.0.1), and #8363 (enabling external storage).

[ManOki]

All my nextcloud clients are not able to connect to server files, if my NAS is offline, i.e. webpage, desktop client, android app..

Other web apps like calendar are still working.

[jospoortvliet]

Should be fixed in 14.0.2, test the release candidate - now out. https://help.nextcloud.com/t/help-testing-rc1-version-of-14-0-2-13-0-7-and-12-0-12/38359

[ManOki]

@jospoortvliet no, the release candidate did not fix my issue. Still getting the same error. Can you reopen the issue?
