26,460 PointsTimeout error after "Check Work" button is clicked after pasting in output from running Systemizer
I ran Systemizer and pasted the following output into the challenge answer field. When I click the "Check Work" button it appears to be checking for about 10-15 seconds and then I get an error message that says:
"Oh no!
We didn't hear from the challenge service in a timely fashion."
Find the output I've pasted in attached below.

26,460 PointsThere's actually a bit more output relating to the OS version, Sun/Oracle info, and user info but even with that included the challenge service still doesn't respond in a "timely fashion". I've checked the network tab in the Chrome dev tools and there are no failed network requests being made (not 500s or anything) so I'm confused about how to proceed from here.

26,460 PointsGood to know. It must be something with my local machine and/or the network I'm on. Had a similar problem not long ago. Thanks for the feedback!

26,460 PointsIn case anyone else finds themselves in a similar predicament, the solution I found was to open a private browsing tab in Chrome and paste my code just as I did before. That's it. It just worked.
Cookies or caching of some sort may have been the culprit here. Anyway, an anonymous session worked for me. Cheers!
