 * I have been trying to set up the FB feed but I keep getting the following error
   when clicking on it in the cPanel:
 * Hosting Server Read Timeout
   HTTP 502 — Unable to Connect to the Origin Server
 * I assume I need to whitelist the plugin in my website’s firewall, but no IP address
   is listed anywhere that I can find

 * Hi [@epzv2y](https://wordpress.org/support/users/epzv2y/),
 * If you have a firewall blocking the Instagram API connection, I would recommend
   adding the domains graph.facebook.com and api.instagram.com to your allow list.
   You can look up the IP addresses associated with those domains if needed.
 * You can also check that your server settings have sufficient resources for time,
   memory and bandwidth.
 * I hope this helps! Please let me know if you have any questions.
 * Best Regards,
