I don’t think this is the source. My answer was Liberia. I was able to spot a .LR domain on a street sign ad.
Then I accidentally lost all progress by clicking the chess notation link and when I got back to the geo guessing it was a small forested area with nowhere to walk to so I gave up :(
it's from fandom.com, so might be out of date. I think the general strategy would work if you had the right list of countries - although if you're determined to just cheat your way past this step, probably better to just look at the source and get coordinates as someone else has suggested.
