Kubernetes admin certificate doesn't fit with my ip adress

My kubernetes master ip is a private IP adress

I can not connect my kubernetes cluser with my gitlab-ci because my IP adress in my admin certificat has my private IP and not my public IP.
When I use curl with -k I I can connect to my cluster but without I got the error than my certificat doesn’t fit with my ip adress. I think Gitlab has the same error.
Is it possible to update my certificat, or create a new certificat ?

Thanks for taking the time to be thorough in your request, it really helps! :blush:
