ERR_SSL_PROTOCOL_ERROR

An SSL protocol error occurs when a website’s SSL certificate is misconfigured, invalid, or cannot be verified. This prevents the browser from establishing a secure connection with the site. The browser may display this as ERR_PROTOCOL_ERROR, a generic error (commonly seen in Chrome) indicating that something went wrong in the communication between your browser and the server—most often related to SSL issues.

Common causes can be

• SSL/TLS issues (wrong certificate setup or protocol mismatch).
• Browser extensions interfering with the request.
