Fix 8: Restart router

Restart your internet router. Just ensure no one else is currently using the internet, as they will lose connection until the router has finished restarting.

If none of the above helped then the site may have blocked your IP or it could be blocking your country for example. So you will need to speak with the site owner to figure out what is going on as the cause is likely due to a firewall setting that they have set up.
