Using Tailscale to access dash app over LAN


I recently installed tailscale on all of my devices and it is working wonderfully. I have one outstanding edge case I would like to solve. It is related to this problem:

I replicated the solution, and ran my custom dash app with host=, port=8050, and then tried to access the app through my tailscale created ip address, but the error message I am getting is ERR_CONNECTION_TIMED_OUT.

Any help would greatly be appreciated. Thanks!
