I have a rural property setup with the following setup

Modem [wired] eap225 outdoor [wired] oc200: Branch 1: [wifi] eap225outdoor [wired] - tp-link 802.af PoE switch - [wired]  2x EAP225 wall.

                                                                           Branch 2: [wifi] eap225 outdoor [wired] d-link poe switch- [wired] eap225 ceiling ap

                                                                           Branch 3: [wifi] eap225 outdoor [ethernet over power] eap225 ceiling ap

The wall eap225s in branch 1 do not seem to be connecting to the OC200 when plugged into the same switch as the EAP225 that is connected to the mesh network. (accessed with iOS device)

When I take them to the structure in branch 2 and connect them to the dlink switch, I can adopt them with the desktop webbrowser. I then brought them over back to branch 1 and plugged in... where they were not detected. After resetting one of them and (and removing the eap225 outdoor from the switch, replacing it by a seperate lte modem), the iOS app now detects both eap225 wall units under the standalone ap section, and correctly detects that the eap225 wall that was not reset as being controlled by the oc200 (but not visible when looking at the oc200 via cloud).

I'm struggling to find what the source of the issue could be in this instance. Any advice?
