Embedding on Wix

Hello,
I have read several help topics on embedding Pollunit in my site (hosted by Wix), and gone through the tutorial more than once, as well as followed everything mentioned, yet my Pollunit won't embed correctly and I get the grey patch with "pollunit refused to connect".

My steps:
On Wix:
Add elements > Embed HTML > Add your code >

On Pollunit
Added hosts under "Allowed hosts"
fileusr.com
www.fileusr.com
www-[mysite]-com.filesusr.com
And of course, copied both the code and auto heigh snippet as well.

However, nothing happens.

I emailed support@pollunit.com 2 days ago and have not received a response.

Is there someone who could assist in seeing where I went wrong?

Thank you!

Hello Muhammad,

Your mail got stuck in our spam folder. I found it but the mail is missing the link to your page. We need this to investigate.

Thanks Markus - I have sent the link via another email just now.

Looking forward to your response.

Your main host was missing in the allowlist.
Wix creates this wrapper iframe with the host www-mysite-com.filesusr.com. You added this correctly but your main domain mysite.com also needs to be in this allowlist. I added it for you and now it works.

Thank you! Really appreciate your assistance.
