Zapier chatbot embed shows a blank box on my html landing page

Built a small FAQ bot in Zapier's chatbot tool using the ChatGPT step and pasted the embed code into a static HTML landing page. Opened locally it's just a white box, on the live server it loads maybe half the time. Does the domain need allowing somewhere?

try it in a private window with extensions off. ad blockers and privacy extensions kill a lot of chat widgets. if it shows up there, nothing is wrong with the embed, it's your browser - though some of your visitors will have the same blockers, so it's worth knowing.

are you opening the html file straight from your computer? a lot of embeds just stay blank on a file:// page and work fine once it's on a real domain. if it's already hosted, check the chatbot is actually published and its access isn't restricted, then look at the browser console for a blocked frame or script error. a content security policy on the page can also block it silently.
