Hi TroelsPetersen-9545,

Service unavailable 503 ,This is likely because the service is busy.

Possible cause of the issue:- Client(Graph Explorer/Postman) would have terminated due the connection timeout at their end.
Try the below options to resolve your issue.

Option 1:- You can make retry requests over a new HTTP connection to fix the issue
Option 2:-Try increasing client side timeout may help in addressing this issue.

Hope this helps.
