Can get Cloudfare Speed test to work

Totally new to Cloudflare so please bare with me. I have just signed up and plan says, Great news! Cloudflare is now protecting your site. However, when I run a speed test, I get a Failed with:

It might have failed because your test URL

domain.com.au

was redirected to a different domain.

Try testing

chrome-error://chromewebdata/

I have no idea what this means? Can anyone help translate and what I need to do to troubleshoot? thanks.

Same problem so glad that someone was able to help. Unbelieveable.

I’m having the same problem as well. There is not much explanation of this result and the next steps. Has anyone been provided with a solution?
