I got to the step 5 but nothing seems to be happening.<p>When I opened the developer console on Chrome, it has these errors:<p>Failed to load resource: the server responded with a status of 400 (OK)
index.js:834 Uncaught InvalidStateError: Failed to read the &#x27;responseText&#x27; property from &#x27;XMLHttpRequest&#x27;: The value is only accessible if the object&#x27;s &#x27;responseType&#x27; is &#x27;&#x27; or &#x27;text&#x27; (was &#x27;arraybuffer&#x27;).<p>I opened the page, then needed to close my laptop for a while before I had done the step where the domain provides certain hash in particular url. Then I got back and provided the url, and it validated, but the step 5 doesn&#x27;t work.<p>Thanks for providing the service!<p>edit: If I now try to do the 4th step again, I get:<p>Error: Domain challenge failed. Please start back at Step 1. {&quot;type&quot;:&quot;urn:acme:error:malformed&quot;,&quot;detail&quot;:&quot;Unable to read&#x2F;verify body :: JWS has invalid anti-replay nonce&quot;,&quot;status&quot;:400}<p>Ok, the error in the api call seems to be &quot;Certificate public key must be different than account key&quot;.
