When certificates were rotated no error gets returned to clients

[Gerrit91]

It can occur that when running metalct, no error gets returned:

❯ metalctl machine console --admin c4601200-6ca8-11ee-8000-7cc2555f87d1
ssh to c4601200-6ca8-11ee-8000-7cc2555f87d1@api.metal-stack.dev:5222
~ ❯ echo $?          
0                                                    

This can happen when for example the certificate was rotated:

{"time":"2025-01-28T12:41:56.141496959Z","level":"ERROR","msg":"failed to connect to management network","error":"tls: failed to verify certificate: x509: certificate signed by unknown authority"}
