E (4441) MQTT_CLIENT: Error create mqtt task

Not exactly sure what the issue is. I have confirmed that the broker is online and functioning and even tested PubSubClient as a control, it worked fine.

Any advise is appreciated. It seems that the MQTT task is failing.

It seems most likely that the configuration is correct but there is not enough memory available to run the ESP-IDF MQTT component which tries to create a Frertos task. You could try to reduce the mqtt_task_stack_size, re-arrange the memory size for other tasks you have, or try the same configuration with another board in order to increase the memory available to be able to create this necessary MQTT task.

Thank you, i thought the same as well, just doesnt make sense. I have 260kb left .. will look into it. Thank you for your time.

I can confirm that changing the task stack size makes 0 difference. I've tried various sizes, as low as 1024, and nothing helps. same exact error. I've implemented other asynchronous MQTT client libs, and they work fine. At this point, i have nothing else that i can try other than to move away from this library.
