Frequently Asked Questions

What causes ERR_SSL_PROTOCOL_ERROR in Chrome?
This error is typically caused by SSL certificate issues on the website's server, antivirus software interfering with SSL connections, outdated Chrome browser, incorrect system date/time, or corrupted browser cache and cookies.
Is ERR_SSL_PROTOCOL_ERROR dangerous?
The error itself is not dangerous - it's Chrome protecting you from potentially insecure connections. However, you should not bypass SSL warnings on sensitive sites like banking or shopping websites.
Why does this error only happen on some websites?
Different websites use different SSL configurations. Some sites may have outdated certificates, weak encryption protocols, or server misconfigurations that trigger Chrome's security checks.
Can I bypass ERR_SSL_PROTOCOL_ERROR?
While you can sometimes bypass this error by clicking 'Advanced' then 'Proceed to site', this is not recommended for sensitive websites as it indicates a genuine security issue with the site's SSL certificate.
Will this error affect other browsers?
Other browsers like Firefox or Edge may also show similar SSL errors for the same website, but they might display different error messages. The underlying SSL issue typically affects all browsers.
