Have your tried the MQ troubleshooting steps described at
this gist

[czongxin]

I use this gist, netclient now is ok, but mq always has error:

i tried to troubleshoot with the given methods, but client connecting and disconnecting it seems.
i my case i added - traefik.http.routers.mqtt_websocket.rule=Host(broker.nekione.com) this label under mq service in docker-compose.yaml. SSL issue is fixed but there is some new issue i just found

No i didn't, i just used an older version of netmaker and it worked for me, also the new release 15.0 is also working great when i last tested.
