Create a Simple JSX Element - url's blocked

Tell us what’s happening:
I am unable to get any React challenges to run as it appears that my access to behind the scenes run-time applications is being blocked by my web administrator. I get this error on all of them “Error: Request errror: 0”. Can you please tell me what url’s needs to be unblocked so I can complete the challenges in this section? Thank you!

Your code so far

const JSX = <h1>Hello JSX!</h1>;

Your browser information:

User Agent is: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.142 Safari/537.36.

Link to the challenge:

Open Developer Tools or Inspect and check “Network” and “Console” log.

I had already checked the console and found these urls:

I just wanted to be sure I gave the correct links to unblock and wasn’t missing anything, or giving incorrect information to my administrator. Thanks.

What is the Status code of those URLs?
It should be 200 not 404 or anything else.

It shows a status of 200 for all the urls but as you can see from the snapshot of my console, something else is definitely going wrong…

Your proxy server is definitely refusing the connection. Right Click on .js files having (failed) status and open in a new Tab.
What do you see?

The page opens up a new window showing the standard error I get whenever the proxy server is blocking a connection (see below). Thanks for your help. I will contact my administrator and see if they can grant access to the links I need.

This site can’t be reached

The connection was reset.


I want to thank you for your help. I worked with my site administrator and the sites causing issues are now unblocked. I ran a couple of the challenges and they are working properly.
