ESP IDF MQTT connection lost after few hours

[nopnop2002]

I have my own server running in a docker, on local hardware.

I don't know the OS of your MQTT server, but I believe you can add Wi-Fi router functionality to this server.

I used Raspbian to build an MQTT server and Hotspot at the same time a long time ago.

I don't want to do anything like this. I plan to use this in an environment with a wifi router and an MQTT server hosted locally or over the internet. Nothing more.
