Can't find deploy process

I publish my package to the Orchestrator
and create an environments and a robot. But when I key the Robot Key and
Orchestrator URL : in my UiPath Robot Settings
it’s is Connected.
But when I want to create processes on my Orchestrator, the error happend with [An error has occured]
and the page reload.

Is anyone has the same problem ?

Is there any specific error message? this happens sometime when server is slow, and sometimes because of user permissions.
