My WDS sta keeps losing dhcp link with the main network randomly and either comes back up after 10 mins or needs a reboot of the repeater.
I was able to gather these logs from the repeater

WDS AP is a mt7621 device on v24.10.0 and WDS sta is a mt7628an device on v23.05.5
The only thing I had changed was setting Force CCMP (AES) as cipher for the WDS backhaul, but now even after setting it back to auto the issue is still present.
