HTTPS connection fail.

[fanmen1]

Hi, I'm trying to send a POST request to a server using my ESP32-S3. The HTTPs connection was working fine until I added some of the mqtt broker connection bits. I'm using the esp_crt_bundle to verify the server. As you can see from the logs, it shows certificate verified, but the connection is failed. Can you please advice on this issue?

It is most likely shortage of internal RAM.
Also check this in config, i had issue recently when set to true with TLS

Code: Select all

config.skip_cert_common_name_check = false;
