Despite some hints and tricks (also discussed in this forum) the MQTT connection was always unstable. Now I have updated to the latest 01.05.02. Using NodeRed or MQTT Explorer with user “bblp” and LAN Password the printer does not respond anymore on port 8883

Anyone successful with MQTT?

No problem here, still able to connect…you used TLS and disabled the certificate?

I am using TLS and disable the certificate validation, but its still used.
Hmm looks like the MQTT client inside NodeRed is still working. Its only the MQTT Explorer who refuses to connect…
