Can't register a machine via HTTP API (if logged out?), only via gRPC/CLI

[joshuataylor]

When using the HTTP API, you can't register a machine, I think it's because I'm logged out. This issue has appeared in the past : https://github.com/juanfont/headscale/issues/749 https://github.com/juanfont/headscale/pull/754

The error is "Cannot register machine: machine not found in registration cache".

gRPC & the CLI seems to work fine.

To Reproduce

1. Login to a namespace
2. Logout
3. Try and connect using the HTTP API

curl:

curl -X 'POST' \
  'https://example.com/api/v1/machine/register?namespace=mynamespace&key=xxx' \
  -H "Authorization: Bearer xxx" \
  -H 'accept: application/json' \
  -d ''

The logs for GRPC shows this, when I do tailscale up:

2022-10-23T09:32:50Z INF ../home/runner/work/headscale/headscale/api.go:255 > New machine not yet in the database follow_up= machine=josh node_key=[V1hiq] node_key_old=

If using HTTP:

I'm having the same issue but with the CLI. I'm unable to make sense of what was done in previous issue reports to fix that, but I'm getting the issue like this:

Client:

$ tailscale up --login-server https://headscale.example.tld 

To authenticate, visit:
    https://headscale.example.tld/register/nodekey:xxx

Server:

$ docker-compose exec headscale headscale -u user nodes register --key nodekey:xxx

Cannot register machine: machine not found in registration cache

Having the same issue on a Windows 11 machine.

Start Tailscale App - Browser opens with the content:

"Machine Registration

Run the command below in the headscale sever to add this machine to your network"

headscale nodes register --user USERNAME --key nodekey:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Ran on headscale server, and get the response:

Cannot register machine: machine not found in registration cache

No idea what to try.
