for anyone looking for the answer. I was able to get it working see below: I was able to get tailscale working after reading many comments it all started to click in my mind and I realized it needed a full url say blabla.local/api… so i was able to adguard home add a dns entry for blabla.local using my tailscale device ip. Reverse proxy on the device aiming the tailscale ip to blabla with the port. Then i found a comment in github comments of old issues the dev mentioned in the data folder of the config files you can change the ip that the api listens so i just changed from local ip to tailscale ip refreshed and it all worked. With no issue to my home browser but api working with tailscale on mobile.
