WordPress Developer + Hide my WP Ghost plugin = app not responding in Cloudron
Just reporting here in case anyone searching the forum about the app not responding for WP developer in Cloudron.
The app does not respond, even after you've restarted the app, just ensure that the route to some paths is not removed/redirected by a plugin, in my case Hide My WP Ghost.
Check the log file in the app's Cloudron setting tab.
In my case, "https://mydomain/wp-includes/version.php" returns 404. So what I did what just revert back the custom wp-includes path to "wp-includes" as it was in original form (see attached below).
Thanks to @nebulon for the help!
