Caused by: java.io.EOFException: SSL peer shut down incorrectly

12 min read

This exception is thrown when the SSL (Secure Sockets Layer) connection was terminated abruptly or prematurely by the SSL peer.

This can happen due to various reasons, including unexpected disconnection, network issues, misconfigured SSL settings, security policies enforced by the SSL server, or even intentional termination by the peer.

To address this issue, you can try the following steps:

  1. Check the SSL configuration: Ensure that the SSL settings on both the client and server sides are correctly configured and compatible with each other. Verify that the SSL version, cipher suites, and protocols are supported by both parties.

  2. Verify network connectivity: Ensure that there are no network issues causing the connection to be interrupted. Check for firewall rules, proxy configurations, or any other network settings that might interfere with the SSL communication.

  3. Check SSL certificate validity: Ensure that the SSL certificate used by the server is valid and trusted by the client. If the certificate has expired or is not trusted, it can cause the SSL peer to shut down the connection unexpectedly.

  4. Inspect server logs: Analyze the server logs for any indications of the cause for the premature SSL shutdown. Look for any error messages, exceptions, or warnings that might provide more details on the issue.

  5. Verify SSL handshake process: Review the SSL handshake process between the client and server. Check if there are any errors during the handshake, such as unsupported cipher suites or protocol versions.

  6. Debug the SSL connection: Enable SSL debugging on the client and server sides to capture more detailed logs and information about the SSL communication. This can help in identifying the root cause of the premature SSL shutdown.

  7. Check for server load or capacity issues: If the server is under heavy load or facing capacity issues, it might terminate SSL connections abruptly. Ensure that the server has enough resources to handle the incoming SSL connections.

If none of the above solutions help, you might need to contact the server administrator or the technical support for further assistance in diagnosing and resolving the issue.
