I am on my 3rd rebuild of OMV 5.n. Nothing I do allows a network connection to an OMV shared folder.
I have turned OFF SMB 1.0 as OMV 5.n uses SMB 2.0-3.0
I have created OMV users same as Win 10 (cams and passwords)
I have tweaked registry all to now avail. Checked FireWall, etc.
I can SEE the RPi OMV device but can't get to the shares. I have even tried using WINS.
And, the OMV IP and Hostname are in the hosts file.
I get a Win 10 error 35 or it hangs.
And, now, with 128bit and password turned off it crashes File Explorer.
But, OMV works great on my Android Note 10. Totally polite...
Microsoft broke the product, probably deliberately as they want everyone to use the Microsoft cloud, not your own.
If anyone comes up with a solution please post.
OMV worked great on my Win 10 Home PC pre version 20H2.
