If you're visiting a website on another server, then it may be that the website is running into a problem, or isn't allowing connections from a VPN.
If the site is on your Linode, there may be a configuration problem. I'd recommend checking the error logs in /var/log for Apache, Nginx, MySQL, or any other services for your site. They can often point you in the right direction for what's causing a 502 error.
