Container manager does not work after update

but dockhand works well

Upd. Few minutes later container manages appear to be disabled so I need to enable it manually.
Upd2. Process redis-server has a permanently high network activity - it constantly consumes 1Mb/s download traffic

Downloaded the update file and log into f4-424 and system said there is a new update 1278, i still use the downloaded file to manual update instead of using the download and update option, everything seems to work fine, will inform if any problem. So I think this is an offical update instead of a beta update. Good Job if there is no problem.
BTW, docker manager work fine for me, I think maybe my system and app (volume 1) are two 256gb NVME M2 SSD Traid help with less problem, I am not sure though.

An old issue has returned—one that hadn't been seen since the very first versions of firmware 7.
It is impossible to access the web interface, yet TNAS PC can see the folders.

Several errors on monitor for F2-424:
CIFS: VFS: cifs_mount failed w/return code = -113
CIFS: VFS: Error connecting to socket. Aborting operation.
Despite the "abort" it still seems to keep trying for several more attempts
