TCP connection reset by peer

When a TCP connection is reset by the peer, it means that the other end of the connection abruptly terminated the connection. This can happen for various reasons:

1. Application or server crash: If the server or application crashes or is forcefully terminated, it may result in a TCP connection reset by the peer.

2. Network issues: Network problems, such as a sudden loss of connectivity or an unreliable connection, can cause the peer to reset the TCP connection.

3. Firewall or security settings: Firewalls or security devices may have rules in place to terminate TCP connections if certain conditions are met, such as exceeding a specified timeout or violating security policies.

4. Overloaded server: If the server becomes overwhelmed with incoming connections or requests, it may reset connections to free up resources.

5. Misconfiguration: Incorrectly configured network devices or software can cause TCP connections to be reset by the peer.

When a TCP connection is reset, both ends of the connection receive a TCP RST (Reset) packet, indicating that the connection has been terminated. The application or software using the TCP connection then needs to handle this event and take appropriate action, such as reconnecting or terminating the connection on its end as well
