Network Storage unreachable after HAOS 15 upgrade

Hi! Did any of you get into trouble with network storage after HAOS 15 update?
Since the update even tho the server logs show a successful login from HA, the network storage doesn’t work. (CIFS protocol, server, share, user and password are all good, server is confirming that)

From the logs:

Any suggestions?

I did some more tests, and it seems like it connects to the Windows machines, it must be a protocol problem between the Mikrotik device, where the NAS is hosted and the HAOS… It’s interesting that the Samba Backup AddOn is working with no issues with the same credentials and the same share/NAS with cifs…
Really weird!
