Zigbee2mqtt became wery unstabel

i have ZBDongle-E coordinator

i had 40 devices and the devices started to become offline and after zigbee2mqtt restarted, they became available again and a couple of hours later some devices became offline. i update the coordinator whit this tool

I installed Multi-PAN(RCP) onto it but I can’t get all the devices. I tried setting up some of the old devices but they don’t want to connect.

so i flash Zigbee (EZSP) 7.3.1.0 this is an updated version of the original firmware

and it is still not working

Hope you find a solution, that said for a setup with 40 devices, I am just guessing that you want it to work…
