The correct URL appears in the browser but the page shows a 404. According to the logs they don’t exist…but they’re there…

It was the first “solution” on google. Didn’t work.

I already went through that. I wouldn’t post here without starting with the official documentation.

This advice is what it is, but I work in a school and Tailscale also seems to be (unintentionally) blocked. After a while I realized it was only the login server that was blocked. If I login using my phone data I can go back to the regular network and it works.
