Testing The Catch Hook Fails

I have a CF7 form (see the code below). I cannot get past testing Step 1 in the Zap setup. The “Send a request to the URL below so we can pull it in as a sample to set up your zap.” keeps spinning and does not finish. This means I cannot see and map all my fields in Zap creation Step 2, where I Create A Ticket (for HubSpot). Help!

=== CF7 Form Code ===

<p>[text first-name placeholder "First Name"]</p>

<p>[text last-name placeholder "Last Name"]</p>

<p>[email* email placeholder “Email (Required)”]</p>

<p>[mask* fw-support-form-phone “(___) ___-____”]</p>

<p>[text* ticket-name placeholder “Issue Name/Title”]</p>

<p>[select* priority include_blank “Low” “Medium” “High”]</p>

<p><label>Reason for contacting us:<span style=”color: red;”>*</span></label><br>
[checkbox* checkbox-reasons use_label_element “Somethings not working.” “I have a question.” “Other”]
[group not-working]
<label>What’s not working?</label>
[checkbox not-working use_label_element exclusive “Can’t access the site.” “A feature is not working.” “A purchase transaction failed.” “Other”]
[/group]
</p>

<p><label>Describe The Issue:<br>
[textarea* ticket-description placeholder “Describe your issue. Provide details like the text in any error messages.”]</label></p>
