For GoDaddy websites you will need to whitelist your domain and the domain of the GoDaddy preview link.
Whitelisting:
Whitelist the GoDaddy preview link
If you find that you can't see the entire widget on the GoDaddy preview link - hit publish and check to see if the widget appears on the published version of your website
After whitelisting our domains, following the GoDaddy documentation here and complete these steps:
Go to your GoDaddy product page.
Scroll to Websites + Marketing and select Manage next to your website to open your site.
Select Edit Website or Edit Site to open your website builder.
Go to the page and location you want to add your custom code, and add a section.
Search for the HTML section and select Add.
Paste the widget code you copied from the OTS Dashboard into the Custom Code field.
