MQTT Explorer not using operating system root trusted certificate authorities

[philipp1992]

Hi,
we are using Windows 11 and when connecting to a MQTT server with certificate validation enabled, we still have to pass a CA-Bundle to make it work, even though the ca is part of the trusted windows CAs. In the browser it also works.
Is this an expected behaviour?
Version: MQTT-Explorer 0.3.5
Kind regards
Philipp

What happens when you don't add a CA bundle? I just found this project and have been trying to set up a connection to a (local) RabbitMQ instance @ mqtt://localhost:1883 and it wont connect, despite the MQTT plugin being enabled and the user being given rull RW permissions.

I wonder if I am running into this same issue as you.

I have Validate Certificate and Encryption disabled:

EDIT: Nope, I'm just a big dummy and forgot to expose 1883 on my docker container that's running RabbitMQ.
