[2021] Core Challenges Unavailable

Hey @tyho5 , welcome to the forums!

I understand you're unable to access the core challenges - sorry about that! Usually, this is caused by something interfering with your connection to the server, where the challenges are stored. As such, I'd like to invite you to check our connectivity guide. In particular, from that article, please remember to reset your network hardware, switch to a wired connection (if possible, and if you aren't already), and check for software conflicts that might be causing interference. 

Let me know if the issue persists thereafter, and I'll have some other steps we can try
