I had a similar issue and it related to the uplink connectivity monitor. Unifi monitors the gateway and controller IP and withdraws the SSID if it can’t contact either of them. Make sure you have turned off wireless meshing on the device and I think you can manually disable the uplink connectivity monitor.

Do you have a continuously running unifi controller or is it only running when you do the config? Does it do the same thing with the controller opposite to how it is now (ie if you aren't running it does it do it when you leave the controller on)?
Are you running the 2.4 and 5 as separate SSIDs or the same one?
Are you on the latest controller and firmware?
Double check the AP doesn't have a DHCP server enabled. Also, check routes and IP settings when a client first connects to the AP and things work, then again when things stop working.
Yep, thanks for checking, there's only 1 DHCP server on my network. I've just moved it back to behind switch B and will do more investigation when the problem occurs again.
