More info on XDN 503

How do I get more details on a deployment that is returning 503 errors?

When requested both the edge and permalink URLs do not produce anything in the Streaming Server output

First, look at the x-xdn-t header:

It can help you understand the path the request is taking through the XDN.

503 means “Service Unavailable”, which, while unlikely, could be coming from the XDN itself or from a backend that your app is proxying. Looking at x-xdn-t is the first step in understanding the source.

The server logs in the XDN developer console will only show log statements (console.log, etc…) that you put in your code. So if you determine that the error might be coming from a fetch call, for example, you can try to try/catch it and write to console.log for more information.
