Cloudflare SSLv3 Alert Handshake Failure

This error message is usually due to an issue with the SSL/TLS handshake process between a client and a server protected by Cloudflare’s security and content delivery services.

According to our experts, this error message means one of the following:

• The client or server may be trying to use SSLv3 protocol, which is no longer supported by many systems. We can resolve this by configuring both the client and the server to use a more secure TLS version.
• If there is a mismatch between the SSL/TLS configuration settings on the client and the server, we will run into the error. For example, the client may be using a cipher suite or security protocol that the server does not support.
• There may be a misconfiguration in the Cloudflare settings that is affecting the SSL/TLS handshake process. In this case, we have to check our Cloudflare settings to ensure they are correctly configured.

Troubleshooting Tips

We can easily resolve this error by ensuring that both the client and server support modern and secure TLS versions. We have to disable SSLv3 if it is enabled.

Additionally, we have to check that the SSL/TLS configuration settings on both the client and server are compatible.

Furthermore, re-check our Cloudflare settings to make sure they are correctly configured for our website or application.
