Ok, so it seems like the issue might be with the link you may have provided. What link did you use for the solution? So far, I tried following this activity on replit, and clicked on “Open in New Tab” and then refreshed and waited like a minute or so, and was eventually able to get the link. I am guessing that might be the issue. Here is a screenshot of what I am referring to (see the button I have pointed out in red):
Once you click on that, you’ll be able to grab the link from the new page. So the solution link you are looking for might be something like: https://boilerplate-infosec.YourReplitUsername.repl.co/
Replace “YourReplitUsername” with your replit username. And then re-submit using the correct link. Let me know if that solves your issue.
