Printer shows DNS failure after update to Core-Update 203

[mepi0011 (Pierre M.)]

I scan from my printer to an SMB release on my NAS.
Since the update to 203, my printer shows me “DNS failure, please check DNS settings.”

Both, the printer and the NAS are in the green network. From my computer (green network), I can ping the printer and NAS by hostname. I can also ping the printer by hostname from the NAS.

A network check on the printer pass with “printer is connected to the network”. I can print the results with the network status. This print shows nothing wrong.

Any idea?

Core Update 203: Recommendations Before and After Upgrading

Regenerate the DHCP configuration The migration from Unbound to Knot Resolver requires the DHCP configuration to be regenerated. Go to Network → DHCP Server and click the Save button (no configuration changes are required). 2. Review DHCP fixed leases and hostnames In CU203, hostnames for DHCP fix…

I followed the three steps in the suggested post, including restarting ipfire. Now the scan is working again. Thank you!
