Troubleshoot a Blank DSH Web UI

Confirm service and asset responses

Request the page and health endpoint directly, then record the HTTP status, headers, and beginning of the body. A connection failure points to the service or port. Once HTML returns 200, reproduce in a private window and preserve the first JavaScript error and failed asset URL. Save evidence before clearing caches.

bash
curl -i http://127.0.0.1:3080/
curl -i http://127.0.0.1:3080/health
