I try to reinstall pyngrok and nothing changed

Welcome to Stack Overflow. Just by posting the error, it is not often sufficient to know what your issue is. You need to also include your code as well as an explanation of what you are doing. While it is stating you are connecting to a site that is using a self-signed certificate, I'm not convinced that is the correct conclusion. Are you using some sort of proxy? — ewokx, Apr 27 '23 at 02:00
