This error is coming when I am trying to refresh the page of Lightning Experience Rollout Specialist Badge.
Also, I have created a component TrailheaDX as part of Challenge 10, it's still showing couldn't find the Lightning Component.Please help

Trailhead Check Challenge Button is not responding back with results.

After clicking on "Check Challange to earn 100 Points", the page keeps loading and answers does not get submitted. Even my friend tried the same.
It seems there is some issue from around 1PM today. Please check and respond me.

I am having trouble completing the challenge for the "Create and Edit Lightning Components" module of the "Lightning Components Basics" trail. Here is the challenge:

Create a camping component that contains a campingHeader and a campingList component.
    The campingList component contains an ordered list of camping supplies that include Bug Spray, Bear Repellant, and Goat Food.
    The campingHeader component contains an H1 heading style with a font size of 18 points and displays 'Camping List'.

Here is my code:

camping.cmp

<aura:component >   
    <c:campingHeader/>
    <c:campingList/>
</aura:component>

campingHeader.cmp

<aura:component >
    <H1>Camping List</H1>
</aura:component>

campingHeader.css

.THIS {
}

H1.THIS {
    font-size: 18px;
}

campingList.cmp

<aura:component >
    <aura:attribute name="campingSupplies" type="List" default="['Bear Repellant', 'Bug Spray', 'Goat Food']" />
</aura:component>

When I check the challenge, I get the error message:

Challenge Not yet complete... here's what's wrong:
The component is not using the correct font size.

Any help is greatly appreciated.

Exact text of error:

Can't figure out whats wrong, everything looks like its working perfectly and I used the examples in the module as a base for the code.
