Hi,

I am not able to establish the WebSocket connection after I update the expired certificates, and the same certificates work fine with the other local server.
Need help in figuring out the issue here.

Thanks in advance!!

Here are the logs:

The log indicates you are trying to authenticate using a certificate with Ed25519 key. Are you sure the server actually supports this key algorithm? As far as we know, support for Ed25519 certificates is still quite rare at the moment. It might be useful to try authenticating using a certificate with RSA or ECDSA key - these are widely supported.

Hi Lukas,
Thanks for the response.
Yes, our server supports the Ed25519 algorithm. It was working perfectly before, I only updated Certificates b'coz older ones were expired. And the same set of new certificates are working with the local server.
And when I use another Algorithm(other than Ed25519), I receive "Fatal error 'HandshakeFailure' has been reported by the remote connection end."

In that case, I would assume that the server was not configured to accept that particular certificate. But regardless, it was the server who closed the connection upon receiving the client certificate and the relevant signature, so the server-side log would hopefully contain information about the actual reason for this. From the client side, it just appears to be a sudden connection closure.
