Hello everyone, I currently have the following problem which I have not been able to locate.

I am running on an RPI Ignition Edge V8.1.37 and I want to connect to my HiveMQ cluster (using ssl) but no matter how much I try to configure the Mqtt Engine to integrate with the server, the connection does not work.

I am carrying out this same test on my PC with Ignition Maker V8.1.39 and it connects without problems.

I leave the RPI log here to see if any of you know what I am omitting.

Thank you

The system date/time on your RPi is probably way wrong.
