microMDM - installing .ipa problem

Hi all, anyone using micromdm for simple tasks? I have mine up and running, but i cant simply install in-house .ipa app

i run

me@mdm:~$ ./install_application 00000000-000000000002001E https://public-server-url/apps/manifest.plist

getting:

  "payload": {
    "command_uuid": "c0000006-0000-0000-0000-af0000c0000d",
    "command": {
      "request_type": "InstallApplication",
      "manifest_url": "https://public-server-url/apps/manifest.plist"
    }
  }
}

in server log i see:

transport=http method=POST status=201 proto=HTTP/2.0 host=10.0.0.227 user_agent=curl/7.68.0 path=/v1/commands
level=info msg="queued event for device" device_udid=00000000-000000000002001E command_uuid=900004e-000-00000-0000-9d000000335 request_type=InstallApplication
transport=http method=PUT status=200 proto=HTTP/2.0 host=81.94.xx.xx user_agent=MDM/1.0 path=/mdm/connect
transport=http method=PUT status=200 proto=HTTP/2.0 host=81.94.xx.xx user_agent=MDM/1.0 path=/mdm/connect

and nothing

lookignat ios logs via Apple Configurator and there is nothing related to mdm or url where manifest file is...

Anyone got it working? If yes, how?

Thank you
