So, I've had this server running with OMV for a couple of months now with no problem at all. It's been working nicely, and I had everything set up as I wanted (it hosts a basic website and stores a bunch of video files which were accessible over SMB shares).
However, the other day I noticed I couldn't access the SMB shares that require authentication anymore. I did a bit of research and came to the conclusion that it's Microsoft's fault (could be an incorrect assumption) with their newest Windows update. I thought I'd write it off as a loss and set up NFS shares. I didn't have much success with that either but, I could still access my files over SCP so I gave up.
Then I thought of setting up FTP. And no. Didn't work. I thought maybe it was my password, so I changed it. Still wouldn't log me in (the error message was saying the creds were wrong but, I know they weren't).
The problem isn't with the protocols themselves, I can still access my files whilst allowing Anonymous connections. But, I don't want Anonymous connections (I don't want my family members to be able to modify the website files, only view the videos). I've even checked the "permit root" login on the FTP service but, I couldn't even authenticate then!
So, I'm thinking there's a problem with the authentication that these services use somehow. But, even then, there should be a problem with SSH, no?
I'm honestly at a loss here. I can't think of what the problem could be or why the issues are suddenly a thing (I only noticed it a couple of days ago).
