I tested it with your project and it didn’t pass the test. I always do this to exclude possible problems with browser plugins.
After the first test, I forked your project and tested again, with a minor change, and it worked. This time, however, even though I passed the challenge, on repl.it the styles weren’t loading (it even returned an error saying it couldn’t find the style.css file).
I tested once again with my project (the one I forked), but this time I copy/pasted your code, exactly as you have it, and it passed the test again.
I can only assume that there’s a problem with repl.it that we cannot fix (they may be working on it), so I would continue with the next lessons and retry later.
One thing you can try is to create a new project (fork the one with problems) and try that one instead.
Finally, you could use something like glitch.com for the same purpose.
