Attached are the publish and subscribe messages. Sorry there is no code case for ESP32 at the moment。

Hi,
I tried and failed to connect, and found the following problems to tell you the following.

  1. The size of the file I made according to the key you provided is inconsistent with that on your instruction. Could you please send the original file of the key to me and try again?

  2. There is a problem with your instruction configuration. When you configure SSL, the SSL_ctxID is inconsistent.

  3. You can try again by adding the following instruction to the ssl configuration.

The AT + QSSLCFG = “sni”, 2, 1
4. You can use the MQTT.FX software to test if your Amazon Cloud is connected properly.
