Issue or Suggestion Description

Hello,

I am encountering and issue with CoreMQTT-Agent when connecting to my AWS IoT endpoint using and ESP32-S3. Upon connection to the endpoint, it looks to hang on my device and it happens intermittently. It has been very confusing to me as I have had no issues before and it has only occurred recently with my CoreMQTT-Agent. After further digging and looking through verbose logs I found something happening within the network transport (mbedtls). It appears to connect to the my IoT endpoint but when initializing the CoreMQTT-Agent task's command loop it look to hangs while waiting for some packets of data.

esp's mbedtls verbose logs:

Is it safe to assume there is something happening between my ESP32-S3 and its connection to the AWS? What I find confusing is that despite the CoreMQTT-Agent task hanging at this mbedtls step, I am still able to perform publishes on my end. If anybody could provide insights in regards to these logs or anything I could look into that would much appreciated.
