Cannot scan to nas drive after firmware Upgrade

[Aaronthurling]

Hi, I upgraded my firmware recently to 20190401 after receiving a prompt on the screen of the printer. Now I am unable to scan to a folder on my NAS. The folder is accessible by all other devices connected to the network, the printer is connected to the same network and this function worked fine for years before this upgrade. Please advise

Most common cause is that the printer now requires SMB2 or 3 and your NAS, if old, is likely set for SMB1, which is a very insecure protocol and one that comes disabled on any new Windows 10 PC. Check for an update for your NAS firmware or you may be able to re-enable SMB V1 on the printer.

Thanks for the reply, yes it seems it is running just SMB, there is an update for the nas that can enable SMB 2 as part of an experimental samba function, apparently it makes the environment unstable in some cases so I’m dubious about doing that. 

In the meantime I’ve discovered a workaround, if the host name is replaced with the Nas IP address in the folder pathway, then it seems to work. I’ve assigned the nas a static IP so it should continue to work. 

Do you see any flaws with this?

If the IP address works then this is not an SMB issue it is a DNS issue. Not uncommon in small networks with no real DNS server on them. Using the IP address is the most common way we configure in business environments.

Interesting, we have several machines that map the nas drive using the host name, mostly windows 10 pcs but also via FileBrowser on iPad. surely if this was a DNS issue then none of those devices would be able to see it this way?
