Text Files from External Storage (CIFS) Cannot be Opened

Steps to reproduce

Unsure if it is reproducible, should be a data base or bad caching in my instance.

1. External storage mounted from SAMBA server (Ubuntu 22.04) to Nextcloud 28.0.6
2. Exsiting Text files where unable to be opened
3. Delete the share, created a new mount and folder (mount point) - same issue
4. Photos were fine, Office documents also fine.

Expected behaviour

Tell us what should happen
Files can be opened as normal

Actual behaviour

Tell us what happens instead
The text editior is forever spinning trying to open a file - new or old

• Note the Redis issue should stem from me restarting the Redis container to try and fix the issue *

Browser log

Insert your browser log here, this could for example include:

a) The javascript console log
b) The network log
c) ...

Start by tracing the text app entry points in apps/text/lib/Service/ApiService.php and apps/text/lib/Controller/SessionController.php for the CIFS file-open request. Review the Redis failure in lib/private/Memcache/Redis.php and reproduce the reported external-storage case if possible. Done means text files on the mounted share open without the loading spinner or connection error.
