Hello Sripriya.

Are you behind a proxy or firewall? When you open ServiceCenter, in the "Monitoring tab --> Environment Health", do you see green for Mobile App Build Service Status?

If it helps, you have the network requirements in the documentation: MABS connectivity requirements



We are using firewall for this. And i could see the red status for the Mobile App Build service in my lifetime server alone. For other dev,test environments it is green in color.

Hello Sripriya.

That means the server doesn't have access to MABS (Mobile Apps Build Service). You need to configure the firewall and other network constraints. Here's what you need: MABS connectivity requirements.


Does anyone have the solution for it?

I am experience the same at my dev environment and i don t want to propagate to QA or Prod.

Thanks in advance
