UI No longer works

[PlayedIn]

I had the zigbee2mqttadminpanel working several months. Wanted to start using it again as I'm going to add a new zigbee2mqtt stick. Whenever I go to https://192.168.1.38:1880/ui I get:
Cannot GET /ui https://192.168.138:1880 brings up node red without a problem.

I updated the node-red-dashboard. That didn't help I deleted the zigbee2mqttadminpanel flow and all the subflows. Imported the zigbee2mqttadminpanel flow back in and corrected the mqtt settings for my setup. I still get Cannot GET /ui

I'm not sure how I borked the config up, but asking for help or ideas. Below is my node red log and also screenshots. I've been getting that length of undefined error for as long as I can remember if I'm not mistaken. I haven't been able to track its origin.

Ok I found that this works: https://192.168.1.38:1880/endpoint/ui and this doesn't: https://192.168.1.38:1880/ui

I only found this by clicking and managing to accidentally trip across an icon in settings that apparently launches the dashboard.

I have no idea why the url requires endpoint. I'll leave this open for a day or so in case anyone might explain.

You have to ask the HA team why they have moved the endpoint and not made it clear.
