P4V can't submit file to NAS: "mkdir: //nas/p4v/: The user name or password is incorrect", credentials ok in windows

Question

P4V is stuggling to submit files to my depot on my nas, error:

2 errors reported mkdir: //nas/p4v/: The user name or password is incorrect. Submit aborted -- fix problems then use 'p4 submit -c 1'. Some file(s) could not be transferred from client.

Now windows have credentials for the drive and I can use it perfectly, the drive is always available. What can I do?

I tried to mess around with sending a password to the depot itself like //nas/p4v/... user/password And many other configurations but p4Admin doesn't like anything past the ... I don't think.
