Certificate problem to access https url

Hello, everyone. Now I am working with betting site.
Here is my URL of problem.
https://yobet.com/game/index/egame_list
So I can access this url with browser, then this url responses with JSON data.
but if I make a request in postman, It doesn’t give any response.
So I thought that It may be certificate problem but I don’t know what I have to do.
Any solution for this?
