How to resolve ERR_SSL_PROTOCOL_ERROR in a secure connection?

Question

I’m trying to establish a secure connection with a website, but I’m getting a cryptic error message that says "ERR_SSL_PROTOCOL_ERROR". I’ve checked my browser settings and the website is definitely using HTTPS, so what could be causing this issue? Is it something wrong with the website itself, or perhaps an issue with my browser or network connection?

Verify website's server-side logs for errors, as ERR_SSL_PROTOCOL_ERROR can be caused by a misconfiguration on the website's end. Check for any SSL/TLS handshake failures or protocol version mismatch issues. If you're unable to access the server logs directly, reach out to the website's support team or webmaster for assistance.

When encountering an ERR_SSL_PROTOCOL_ERROR, it's essential to investigate possible causes beyond just website configuration or browser issues. A more in-depth analysis is necessary to determine whether the problem lies with the user's network settings or external factors such as a blocked HTTPS connection due to firewall rules. Checking if any firewall rules or proxy settings are interfering with the secure connection can often resolve the issue.

Check if the website's server-side software has been compromised or is outdated, as it may be vulnerable to security issues. Outdated plugins, such as SSL/TLS versions 1.0 and 1.1, can cause the ERR_SSL_PROTOCOL_ERROR error. Inspect the website's HTTP headers for any signs of tampering or unusual settings.
