Facing the same issue. Whatever I try, I’m getting a 404. I added an ingress with a dedicated domain for the developer and configured the same domain in the dashboard (Your developer portal -> Set your portal domain). I also tried hardcoding it in the tyk_analytics.conf. No dice.
Can someone please offer some insight? The docs keep recommending to add the portal domain to etc/hosts. I even tried that, but still no luck.
Using the ORG ID in the dashboard URL (like bmcgough suggests) does work, but clicking on any other link will break it, because it uses a different root URL.
