Hello,

Thanks for reaching out and for using BoldGrid’s Speed Coach website performance test.

I’m sorry to hear your having problems with Speed Coach. One common issue I always see is, if you’re entering your website address exactly like you did in this question, i.e. www.example.com, the reason the test is failing is because there is no DNS for the www. sub-sub-domain.

Instead, enter your website address like so: development.example.com.

I hope this helps. Please let us know if you have any other questions for us.
