protocol websockets

I believe this could work but I doubt you'll be able to make it work using let's encrypt, you'll probably need you own certificates.

Yes, without reverse proxy, client cert authentication works perfect with own ca. but behind traefik it doesn’t work,,
Thank you

Hi, a doubt..in your docker-compose file why are you using the entrypoint for 8883 if you are using the websecure entrypoint in the mqtt section config?

@iboluda The 8883 entry point is for TCP connections while the 443 is for web sockets, does that answer your question ?

Thanks for clarify me that point. Yes that answer my question
