Analysis

The stacktrace indicates that the client crash was caused by a java.net.SocketException: Connection reset error. This error occurs when the client attempts to establish a connection to a server, but the server resets the connection before the client can complete the handshake.

The error is suppressed multiple times, indicating that the client is attempting to recover from the error by retrying the connection. However, the error persists, and the client eventually crashes.

Possible Causes

There are several possible causes for this error:

Server-side issue: The server may be experiencing issues that are causing it to reset the connection. This could be due to a variety of factors, such as a server overload or a misconfigured server.
Client-side issue: The client may be experiencing issues that are causing it to attempt to establish a connection to the server multiple times, leading to the error.
Network issue: The network connection between the client and the server may be experiencing issues, such as a slow or unreliable connection.

Conclusion

In conclusion, the client crash was caused by a java.net.SocketException: Connection reset error. The error is suppressed multiple times, indicating that the client is attempting to recover from the error by retrying the connection. However, the error persists, and the client eventually crashes.

To resolve this issue, we need to investigate the possible causes and take steps to address them. This may involve working with the server administrators to resolve any server-side issues, or modifying the client code to handle the error more robustly.

Recommendations

Based on the analysis, we recommend the following:

Investigate server-side issues: Work with the server administrators to resolve any server-side issues that may be causing the error.
Modify client code: Modify the client code to handle the error more robustly, such as by implementing a retry mechanism or by using a more reliable connection method.
Monitor network connection: Monitor the network connection between the client and the server to ensure that it is stable and reliable.

Introduction
