Recently for a duration of 3 minutes i observed that my device is send [TCP Previous segment not captured] , Ignored Unknown Record gradually. Also there seems to be other warning packet sent from the device including TCP window full. The server responds to none of it. Could anyone able to find where exactly the issue is rooted? What does it mean by ignored unknown record, window size full, encrypted heartbeat. Any help would be appreciated.
Below are the suspicious packets sent from the device end which is found on the wireshark trace.
