Tasmota and wildcard certificate MQTT

[Tam481]

Hello,

Do you know if Tasmota supports wildcard certificates?

I run my MQTT behind a reverse proxy (Traefik). If I set the hostname for the MQTT server to a named host ("mqtt.example.com") MQTT Explorer and other applications work fine and are able to connect. However, Tasmota devices stop working and report that they are unable to connect to the server. If I change the host to be ("*") then they start working again. I'm using a wildcard certificate by Let's Encrypt as I run multiple services behind Traefik.

Thank you in advance

I don’t know but the Result Code from the MQTT failure would be helpful to identify the issue.

 

MQTT - Tasmota has some useful information. The issue may be a timeout but without further background it’s difficult to say.

 

Regards

Here's the error I'm getting.

TLS connection error: 0

Connect failed to mqtt.example.com:8883, rc -4. Retry in 10 sec

`TLS connection error: 0` means that TLS phase succeeded.

Error -4 means:  MQTT_CONNECTION_TIMEOUT (the server didn't respond within the keepalive time)

Hope this helps.
