Hello,

Some time ago I setup Tailscale with Railway to access my db using a private connection. I really like that this is possible!

My key just expired yesterday and I was trying to follow the tutorial on tailscale on how to reauthenticate the tailscale service in railway: https://tailscale.com/kb/1028/key-expiry?q=key+expiry

However, I could not figure out how to do this. I tried connecting to the tailscale service using railway link and railway ssh and running

```
tailscale up --force-reauth --accept-dns=false --advertise-routes=fd12::/16 --hostname=mundu-backend-production
```

This crashed the tailscale service in the railway project, and I got it back up by redeploying it.

The I got the tailscale+railway working by extending the key expiry and then disabling key expiry (in the Tailscale UI), but I am not sure if that is best practice... Can you tell me how your approach would be to reauthenticate the tailscale service in railway, so I can re-enable the key expiry?

Best regards,
Jón
