Describe the issue you are experiencing

The OpenThread Border Router AddOn has a status webpage, defaults to port 8080 and an api on port 8081 which is useful to check mesh Topology and such.

Please migrate these to the ingress system built into HA.

Right now, the interface must be accessed over http because the frontend on port 8080 calls port 8081 over http which causes a mixed content error.

Usage of HTTP in browsers is entirely blocked on my domain due to preloaded HSTS.

An additional bug, content is being sent to the user using content-type text/plain, which causes X-Content-Type-Options: nosniff to block it.

Home Assistant OS

Which operating system are you running on?
