Hi, as an absolute beginner I couldn't find any solution to the problem. the following code keeps throwing exceptions and I do not know why?

and viewing the result obtained by the serial monitor I get the following problem

resolved exception 29 error by removing progmem which stores information directly in the flash which caused auto resetting in ESP8266, plus added ip connection for successfull connection with MQTT.
