Cant run in sandbox

I am using Modeler 5.3.2 and i am trying to run an App in Sandbox so I imported the AppCloudServices, but when i call the StartAppCloudServices microflow in the settings/Model/after startup my App does not want to run in Sandbox. When i remove that microflow call the App runs in Sandbox but i can not log in with Admin details?

Going to bump this again. Really need some more information about the errors we are getting - there is no stacktrace or information in the Modeler, nor in the deploy screen at Just "oops, something went wrong".

It could be a java conflict, how will we now? Perhaps a connection timeout? No idea

We have followed the exact steps in the guide at

Pretty sure we've done everything correctly. What hidden conditions are not being met?
