Product: LJ M477
Operating System: Unknown

Hi, I have a new LJ M477. I set up 4 scan addresses on my Qnap NAS and it was all working fine until I updated my NAS and Router firmware a few days ago. I get the error "test was unsuccessful. Try again" 

I can ping the DNS of both the NAS and the M477 successfully. I can scan using the HP utility from PC. SMB 1-3 are active on the Qnap NAS. I can see & access the network drives fine from my PC's and tablets. I have tried deleting all the entries on printer and redoing. I have reset the printer. I've rebooted router, NAS etc. I can access printer EWS fine and do the setup of the scan to Network entries OK. Any thoughts on what might be causing this issue?

In the authentication settings, I have found that in some cases you need to enter the user name as domain\username.

New units often ship with outdated firmware.  Current date code should be 20190113.

Thanks Repairatrooper. I upgraded the firmware when I first Setup the M477 and am on the 20190113 version. So that doesn't seem to be the issue.

Well done. This fixed my issue. While previously I could get to the shared network drive without the need for credentials the latest update seems now to be enforcing the need. I entered the domain/user name and password and away it went.
