Hello Community,
I am encountering an error after my STM32H7ZIT6 device runs for a few hours. The device is intended to send and receive data from AWS. The error logs show repeated instances of mbedtls_ssl_read_record() returned -27648 (-0x6c00), ultimately resulting in net_recv failed - -109
Error Logs:

I would appreciate any suggestions on potential causes and solutions for this issue. If there are any known issues or patches related to this error, please let me know.
Thank you
