takes very long time to connect on ESP32

[shubhamsharmaa001]

example used - Esp32-lwmqtt

These are the logs of my esp32 . Number 2 to 15 in the logs represent retries to connect to server.

Why is it taking so long to connect??

Note - (Number 1 retry and logs before it are missing in these logs)
