I've tried to use the command passenger-config restart-app and to add/edit the file restart.txt in the tmp folder from article Restarting applications - Apache - Passenger Library and both methods are working correctly. But the restart button still doesn´t work... I will open an issue, thanks...
@Anthony, I have some problems with the restart button, it doesn't seems to work properly.
I need to disable the application and then enable it again to apply the changes :(
As a suggestion, I have an automatic pipeline that compile the app and upload it using ftp, but I need to manualy restart...
