Tracker says "Network Error" when I try to search a username

When I load onto the website and try to search not just my username but anyone’s a message appears in the box where there would usually be usernames that claims there is a “Network Error”. I am connected to internet obviously and I’ve been attempting to use the site for a few days now with no success. However I downloaded the mobile app on my phone and It seems to work perfectly fine when I search my stats. Another thing that was interesting was I tried to search my stats on the computers at my school and it actually came up. So there must be something different about my PC that’s not registering something. Has this happened to others? Is this something I can fix?
