Yes, it’s possible to use a single SSL certificate across all hosts in your cluster, but it depends on how your domains are set up. If all hosts share the same base domain (like host1.example.com, host2.example.com), you can use a wildcard SSL or a multi-domain (SAN) SSL certificate that covers all hostnames. Install the same cert and key on each node. This avoids creating separate CSRs and renewals for every host. Just note that sharing one private key across multiple servers can be a small security risk if one host is compromised. Hope it helps! ... View more

The error ERR_BAD_SSL_CLIENT_AUTH_CERT is a security-related bug that appears in web browsers, especially Google Chrome, due to a failure to interact with the SSL/TLS client authentication process.  This issue arises when SSL/TLS certificates are required on both client and server sides, but the client fails to present a valid certificate or the server can't verify it.
