Understanding the Issue

WP Umbrella uses the WordPress REST API to manage plugins, themes, and other site components on your WordPress site. However, communication issues can occasionally occur, usually due to either your hosting provider's firewall blocking WP Umbrella, or WP Umbrella being blocked by your security plugin.

Whitelisting WP Umbrella's IP in Security Plugins and Services

You need to whitelist our server IP addresses (IPv4: 141.95.192.2 and IPv6: 2001:41d0:306:1702::/64) in your security services or plugins, and verify if they are blocking access to the WordPress REST API. Here are specific guides for whitelisting WP Umbrella's IP in various security plugins and services:

Contacting Your Hosting Provider

If you don't use a security plugin or continue to experience communication issues after whitelisting WP Umbrella's IP, it's time to contact your hosting provider. Open a support ticket and send them the following message:

Troubleshooting / FAQ

If the issue persists, make sure that you are not geoblocking France - our servers are hosted there.
If the issue still persists, make sure that your security plugin is not restricting the use of the REST API of WordPress.
If the issue still persists, try to disable all security plugins temporarily and check if WP Umbrella can connect to your WordPress site. If it works, enable the security plugins one by one to identify which one is causing the issue.
