How to rotate WebUI only certs

Hello, I have a problem with a development cluster that I installed a year ago, I rotated the certs about a month ago following this doc https://rancher.com/docs/rancher/v2.x/en/cluster-admin/certificate-rotation but the certificate from the web-ui was not rotated, is the “dynamic” one, so the cattle-node-agents complain about it.

I already deleted the file dynamic-cert.json and the secret k3s-serving, they were recreated and updated, however, the webui still uses an old certificate that I can’t find, where is this certificate? How do I renew it?

The rancher version is 2.4.15 and was deployed with docker.

Wow, it is what it is then

There isn’t any solution? We are about to hit the same wall…
