I have a docker stack consisting of caddy and wordpress currently in development at https://localhost and I am getting two critical erros:
I am not sure what could be causing this
The REST API encountered an error Performance The REST API is one way that WordPress and other applications communicate with the server. For example, the block editor screen relies on the REST API to display and save your posts and pages. When testing the REST API, an error was encountered: REST API Endpoint: https://localhost/wp-json/wp/v2/types/post?context=edit REST API Response: (http_request_failed) cURL error 7: Failed to connect to localhost port 443 after 0 ms: Couldn't connect to server and
Your site could not complete a loopback request Performance Loopback requests are used to run scheduled events, and are also used by the built-in editors for themes and plugins to verify code stability. The loopback request to your site failed, this means features relying on them are not currently working as expected. Error: cURL error 7: Failed to connect to localhost port 443 after 0 ms: Couldn't connect to server (http_request_failed) I am not sure if this will solve by itself in prod
here is my compose file; DOMAIN_URL=https://localhost :
