Server Registration Failed

[tinasherobert]

Please help Im trying to add the device to the user account that we have created from the web panel but it keep on saying :

token is blank you likely need to update the web application and/or restart the ODM app to re-register.

It is working perfectly fine on the localhost but on the our website backend it is not.
