Hello @Lương Phạm Thái Huy or @lngphmthihuymr-6536
Thank you for posting this concern on this community space.
I was reading your case scenario issue and I would like to gather the following option as it is shown down below:
Based on your error message, the following PIP (Public IP) named "Vinparking-GW-IP" is being mapped to a Virtual network Gateway or Load balancer or any other compute resource... Isn't it?
Well, you can do a force deletion or detach this PIP from any compute resource first and then delete it.
Let me know if that was useful but if not, I can keep assisting you further.
Looking forward to your feedback,
Cheers,
