hi guys, could someone help with rancher cluster? i am facing issues after updating certs to the custom one

Get "<https://10.43.116.54/k8s/clusters/c-m-gz28sbhl/version?timeout=15s>": net/http: request canceled (Client.Timeout exceeded while awaiting headers)

force update is not working and cluster agents are full with these logs
