Cloudflare could be the problem, but not sure

Ok So I'm somehow reading through tutorials because I love reading tutorials I ended setting up cloud flare on my pc
and I don't know how to remove it or reset it I didn't do an account all I did was change a few numbers on ip4 and ip6

Now all I want to do is download a few mods for my game but every time I go to this website I get this error and this error is the same for chrome edge and fire fox
1 is there something wrong with the site or my firewall or what is going on
2 is there an alternative

Thanks

1. We don't know what you "setup" from Cloudflare. They have many products ranging from just using their DNS or VPN etc
2. Is the issue only with a single site, multiple or all sites?


I'm assuming you just changed your DNS, you can go into your network adapter settings and just change DNS back to automatic and that should point DNS back to whatever is being supplied by your router
