# Fixing ERR_SSL_PROTOCOL_ERROR and SSL handshake errors

> What "This site can't provide a secure connection" means and how to fix it, on the website side and on the visitor's device.

**"This site can't provide a secure connection"** (`ERR_SSL_PROTOCOL_ERROR`), `SSL_ERROR_RX_RECORD_TOO_LONG` and "SSL handshake failed" mean the browser and server couldn't agree on a secure connection at all. It usually means HTTPS isn't set up for that address yet, or something on the visitor's side is interfering.

## If you own the website

**1. Is there a certificate for this exact address?** In cPanel, open **SSL/TLS Status** and check the domain and `www` have a green padlock. If not, click **Run AutoSSL**. See [Why AutoSSL didn't issue a certificate](https://helpcenter.ruachost.com/ssl-security/ssl-troubleshooting/autossl-not-issuing/).

**2. Does the domain point to Ruachost?** If DNS still points to an old host, visitors reach a server with no certificate for your site. Check your nameservers and A record. See [My DNS changes aren't working](https://helpcenter.ruachost.com/domains/dns/dns-changes-not-working/).

**3. Using Cloudflare?** A brand-new domain on Cloudflare can take up to 24 hours to get its edge certificate. Check **SSL/TLS → Edge Certificates** in Cloudflare.

**4. Recently installed a paid certificate?** Make sure the certificate, private key and CA bundle all match. Reinstall in **SSL/TLS → Manage SSL sites** using **Autofill by Certificate**.

## If only some visitors see it

The problem is usually on their device or network:

- Check the device's **date and time** are correct.
- Clear the browser cache and SSL state, or try another browser.
- Turn off antivirus "HTTPS scanning" or a VPN temporarily.
- Try a different network, such as mobile data. Some public or office networks interfere with HTTPS.
- Update the browser and operating system. Very old devices may not support the modern TLS versions our servers use. See [TLS and cipher suites update](https://helpcenter.ruachost.com/ssl-security/website-security/tls-and-cipher-suites-update/).
