[SOLVED] Can't access shared machine

I have a shared machine with a friend.

My friend installed the Tailscale android app and loge in with the email that i shared the machine with.

She can see the machine in his app and on the web dashboard (with services and everything) but when she types the ip and port in a browser he cant access, also tried with the magic dns full domain but not working.

I have added his email to the Access Control Json but still cant access, any idea how to solve this

solved it
I forgot to add the "Users": ["autogroup:shared"] in the Access Control Json
