Response to Error: net::ERR_SSL_VERSION_OR_CIPHER_MISMATCH
When trying to access:
https://portfolio.demo.zama.ai/faucet
I encountered the following error:
net::ERR_SSL_VERSION_OR_CIPHER_MISMATCH
This typically means that the browser couldn’t establish a secure connection with the server due to one of the following:
The server is using an outdated TLS version (e.g., TLS 1.0 or 1.1) which is no longer supported by modern browsers.
The SSL certificate may be expired, invalid, or misconfigured.
There is a cipher suite incompatibility between the client and server.
If you’re a user:
- Try using another modern browser (Chrome, Firefox, Brave).
- Clear your browser cache and DNS.
- Try from a different network (some corporate VPNs or ISPs may block older TLS/certificates).
If you’re from the Zama team:
- Ensure the server supports at least TLS 1.2 or preferably TLS 1.3.
- Test the SSL config using [SSL Labs]
- Check for any outdated or insecure cipher suites being used.
- Consider renewing or reissuing the certificate via Let’s Encrypt or your current CA.
