The S in HTTPS would be my suspect #1 when using some sort of intermediary server which may not match the TLS certificate in use/expected, or may not use a recognized root CA. Thanks!

I am not using Arduino but ESP-IDF. I will give this a try on that system and see what I get.

I used to have my website URL configured using a simple dynamic DNS service. I have my device's firmware files on my server, and I was able to use the ESP-IDF OTA functions to do a firmware update by accessing the firmware file at a URL pointing to my website. I recently changed internet services an...

I've used ESP-IDF 4.4 implementing a web server and have not experienced a memory leak.

Have you tried logging debug messages to the console to see what's going on?

Your question is cross-posted...
