Did you upgrade the switch FW recently? What is the version of your controller?

 

You may confirm the switch settings on the Controller, that the uplink port(to your router/DHCP server) has profile "ALL"

 

BTW did you set up the legal dhcp server？ Try disable it if possible.

 

The switch software was upgraded from 1.0.09 to 1.0.10 after the issue started. I downgraded it as well. The software controller upgraded from 4.4.4 to 5.7.4, but this occurred after the switch stopped passing VLAN traffic. DHCP is disabled on the switch. The router handles all of that. All port profiles were set to all. I gave up and replaced it with a mikrotik cloud switch and all is well.
