Error can occur when visiting a website even in modern browsers.

This message is sometimes displayed when accessing an SSL page via a proxy (including our own payment page PayPal). It is caused by Chrome being unable to render the 502/302 proxy response for some sites (Issue 119713). Check your browsers Proxy settings. If possible remove the proxy and try again. To change this setting, go to [chrome://chrome/settings/](chrome://chrome/settings/) Then Click `Show Advanced Settings`. Scroll down to `Network` and click `Change proxy settings…` Uncheck `Automatically Detect`.

This usually means the implementation of SSL on your server is not correct. The error is usually caused by a server side problem which the server administrator will need to investigate. Below are some things we recommend trying. - Ensure that port 443 is open and enabled on your server. This is the standard port for https communications. - If SSL is using a non-standard port then FireFox 3 can sometimes give this error. Ensure SSL is running on port 443. - If using Apache2 check that you are using port 443 for SSL. This can be done by setting the ports.conf file as follows `— clip — Listen 80 Listen 443 https — clip —` - Make sure you do not have more than one SSL certificate sharing the same IP. Please ensure that all SSL certificates utilise their own dedicated IP. - If using Apache2 check your vhost config. Some users have reported changing `<VirtualHost>` to `_default_` resolved the error.
