I do not understand the meaning of "gateway 504". What is the meaning of "gateway 504"? Does it mean you are 'ban'? Well, I tried to access a site, but I keep receiving those messages. I didn't do anything wrong -- what does it mean? How did you know if you are ban from a site? Are you going to receive a notification or what? -- just asking.
