Why am I getting 504 Gateway Time-out Error

Whenever I am trying to access Steemit.com from my laptop I am getting 504 Gateway Time-out Error. Below I have attached a Screenshot so that you guys will know what I am talking about.

I normally use Google Chrome and I was getting the error so I thought to use a different browser and check. And I got the same result. I am new here and I want to explore and learn about it. I am keen on sharing new stuff and earn a little bit of money from Steemit.

I have seen many people who are earning a lot of money but if I am not able to access Steemit.com then how can I post and how can I earn money.

Please help me and also share your knowledge with a noob like me.

Thank you.
