Failed protocol test

[ghost]

dokku monit:config [MY-APP] returns empty result. Also file /home/dokku/MY-APP/monitrc is empty.

Is this by default? I am getting following error when I enable Monit for my app:
failed protocol test [HTTP] at [localhost]:443/ [TCP/IP SSL] -- HTTP error: Server returned status 405

Any advice would be greatly appreciated.

OK, so I need to enable monit for my app in order to generate monitrc config file. Still the failed protocol test persists.
