Can't access OMV shares from domain user account

So I have OMV set up and sharing some folders over SMB. I can get OMV to prompt me for credentials, but can't connect. I have tried username@domain, and .\username but neither works. I'm guessing it's because OMV is sharing via WORKGROUP, but changing that to my domain didn't help either. Thoughts?

This can be close. I must have fat fingered setting my password. Works after a reset.
