SSH Tunnel with browser rendering

I believe I have my SSH tunnel set up correctly, and I’ve enabled browser rendering. After I enter my pin number from the auth email instead of an browser SSH console I get an error which says “Unable to connect to origin. Please confirm that the tunnel is set up correctly and the origin is healthy.” The origin is healthy and the tunnel is up. Not sure what the deal is.

Should also mention I have other http(s) services running over the tunnel and they are working fine. It’s just SSH that is the problem.
