SSL: WRONG_VERSION_NUMBER is an error that occurs when a client tries to establish an SSL/TLS connection with a server using an unsupported protocol version. This error typically occurs when the server only supports older versions of SSL/TLS, and the client is using a newer version that is not compatible. It can also occur when the client or server is configured to use a different protocol version than the one expected by the other party.
Check the SSL/TLS versions: Ensure that the SSL/TLS versions used by the client and server are compatible. If the server only supports SSLv3 and the client is using TLSv1.2, this error can occur.
Check the protocol: Ensure that the protocol being used is correct. For example, if the server is expecting HTTPS traffic but the client is sending plain HTTP traffic, this error can occur.
Update your software: Ensure that both the client and server software are up to date with the latest security patches and updates. This can help prevent compatibility issues and other SSL/TLS errors.
Check the firewall settings: Check that the firewall settings on the server or client are not blocking SSL/TLS traffic. Some firewalls may block SSL/TLS traffic by default, causing this error to occur.
Check the certificates: Ensure that the SSL/TLS certificates used by the client and server are valid and properly configured. An invalid or improperly configured certificate can cause this error.
Disable SSLv3: If the server only supports SSLv3 and you cannot update the server software, consider disabling SSLv3 on the client side to avoid compatibility issues.
By following these steps, you can troubleshoot and solve the SSL: WRONG_VERSION_NUMBER error, ensuring secure and reliable communication between the client and server.
