Lets take a look at the response

sudo tcpdump -i any -s0 -w linkwarden.pcap -v port 3000
kubectl create job antirot-manual --from=cronjob/anti-link-rot

Looks like it's an auth issue

Packet capture screenshot, shows we're getting a 401 back

Which is a little odd. The request clearly includes an auth header with a bearer token.

Looking in Linkwarden, the token's not expired:

I created a new one and updated the secret in k8s.

This time, it's run fine

We can obvs improve a bit here by having the code handle the auth failure, but it's not clear why the token suddenly stopped working.
