Hello I am from Russia. And your website (fiveM.net) is blocked by our government. (IP: 104.28.30.101)
I can go to your site through an anonymizer, download fiveM, but there is no way to install it, because the server is connected to fiveM.
You should contact your government and tell them to stop blocking entire IP addresses because of one malicious site being hosted on them. We are using Cloudflare for our web services for various reasons, and they share IP addresses between a very large amount of websites.
