I can successfully log into the home assistant ssh service using remote.it, however when I try accessing the web service at http://localhost:8123 I get an http 400: bad request error.
I have home assistant hosted on a linux system and I can access an apache server at http://localhost just fine.
Figured out the problem. Had to enable reverse proxies in the Home Assistant http server by using the trusted_proxies: 127.0.0.1 option in the HA configuration.yaml.
Thanks for the update on this, for everyone else, in your configuration.yaml file, edit the http setting like so:
http:
# You must set the trusted proxy IP address so that Home Assistant will properly accept connections
# Set this to your Remoteit Jumpbox IP, or localhost if if remote.it is running on the same machine as home assistant.
trusted_proxies: 127.0.0.1
