NodeRED add-on direct access with Safari = connection lost

I have the NodeRED add-on set up with my Home Assistant (a.k.a. Hassio) installed on my intel NUC. I can access nodeRed through the front end / ingress without issue.

I connect, the flow page loads, but then a few seconds later I get this:

Using the developer tools in safari, I can see that I the websocket connection is returning a 401 error:

This also happens in safari on the ipad/iphone. Anyone getting this to work?
