Is there any proxy (other machine) between VPS and Facebook?

I made Facebook Login button for a site, on localhost it works but on DO VPS it doesn’t. I am thinking that requests from VPS -> Facebook are changed, goes through another machine before reaching Facebook. Here are all details

I don’t know what to do and what/how to debug this problem.


On Monday-Tuesday I will move everything from DO to other server, and will see if it helps.

The support guy said that there is nothing in between my VPS and Facebook.

Then I have no idea what to do next.

Hi @arteniioleg

  • Go to the Facebook App Settings webpage.
  • Check that you have the correct URL for your website website’s URL.
  • Also double check that your domain is added to the “App Domains” section (without http://)
