Roblox doesn’t support HTTPS so I decided to go on and change the beginning of the URL to HTTP, and you want to know what happened? The same error happen again, because of that, I decided to search on google the error “URL must be http,” and do you want to know something absolutely hysterical?
You dont nessecarly need to create a proxy to access this information as there are publicly available proxies for you to use. (Ex: Roproxy), But for that case, make sure you are writing the exact URL with the proper information, as an incorrect value can give you incorrect results.
