Form not working with https

Hi, i am using https through cloudflare.
And i have created a form + landing page on mautic.
The url is https://mka.smartlaunch.pt/fuckup-nights-sign-up
It works on desktop, but it does not load on ipad or iphone.

To open the form on ipad or iphone i have to use the url without the s from https.
Like this: https://mka.smartlaunch.pt/fuckup-nights-sign-up

To see the logo at the top of the page i had to remove the s from https from the img src also.

Can someone help me?
Thanks
Sofia
