HTML Introduction to HTML and CSS Getting Familiar with HTML and CSS Test: Changing the Look of a Web Page

I continue to receive the message "oh no, there was a communication error" when I attempt to click the "check work".

I seemingly am not able to process through the "check work" portion of this challenge.

May I receive some assistance?

Hi Angela. I've had some frustrating problems with that in the past as well. I would say you should try closing your browser and reopening it to see if you have better luck then. If that doesn't work, it make be more fruitful to contact support. I don't think the staff checks the forum very often for technical support questions, so going straight to support would probably get you a solution more quickly. Good luck!

The root cause of the issue I was experiencing was that I was leveraging my employers network and computer for this course work. Company policies prevent external uploads, so I was receiving the communication error.

Now, I know I have to use my personal laptop to complete the challenges that require me to upload code for review.
