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. Common causes include certificate misconfiguration, incorrect device date/time, software issues, or interference from browser extensions and antivirus programs. There are many different ways to fix the error which you need to understand properly in detail.
