iFrame to a HA Dashboard using a exposed a port

[rodrigo-wa]

Hello,

When I use an ingress mode, a dashboard url (/dashboard-floor/floor) works like a charm into a iFrame sidebar view... but when I try the same url in the exposed port, it won't work and just show me a black page. I have exposed a port in the add-on configuration (8686).

Can you help me, please?! Any suggestions?!

Tks
