Ubuntu 20.04 - need help with mounting Windows Server NFS

I got mounting to work, used:
sudo mount.cifs //192.168.10.101/Users/User1/Documents/Jagatud -o credentials=/.smbcredentials /mnt/shares
Now I try to automate this by adding this to /etc/fstab
//192.168.10.101/Users/User1/Documents/Jagatud /mnt/shares cifs credentials=/.smbcredentials,iocharset=utf8,sec=ntlm 0 0 this is not working for some reason. When I do sudo mount -a I get error.

Unable to select appropriate authentication method!
Send error in SessSetup = -22
cifs_mount failed w/return code = -2
No such file or directory.

Any ideas?
