Hi Kevin,
Its very dependent on what the issue is as to what error codes could appear. For example if its a call to an API then the following page might help: Analytics Error Handling.
Maybe others in the community can chip in with anything they look out for with specific scenarios etc
Often from a product support side, if there isn't anything obvious in the logs, they will use the correlationID from the network logs to check what happened on the backend.
