After connecting to the MQTT broker, after a few hours, the message "esp-tls: couldn't get hostname for :xxxxxx.ap-northeast-1.amazonaws.com: getaddrinfo() returns 202, addrinfo=0x0" suddenly appears, and the connection is disconnected. (CA-303) #192

We are using the W5500 Ethernet chip for MQTT communication with AWS IoT over Ethernet. We have loaded the necessary certificates onto the device, and the connection with the MQTT broker works fine initially.

However, after maintaining the connection for some time, we encounter the following error:

"E (25774312) esp-tls: couldn't get hostname for :xxxxx-ats.iot.ap-northeast-1.amazonaws.com: getaddrinfo() returns 202, addrinfo=0x0"

Could you please explain what might be causing this issue and if there are any workarounds to resolve it?
