ESP resets after Attempting MQTT connection...

[BenediktMiller]

Hey,

I am running into some issues using the DER example. I am using the example sketch and right after attempting to create the MQTT Connection the ESP resets.

This is the full serial monitor output:

Could this be the result of a faulty esp8266 or some wrong configuration?

Any help would be greatly appreciated.

Did you solve ? I have exactly same issue.

[nhlives]

Me too

I solved, downgrade the pubsubclient's lib version and the esp's version too.

It would be helpful to know what versions you used :-)
