Reset pwd page not opening on iphone

Hi everyone in this forum,

I created/updated the reset page, test it and it’s working on desktop - safari.

However on my iphone it’s not working. When I click on the “Reset password” link within the email to recover the password on my iphone, I get the following message on Safari “Safari can’t open the page because secure connection can’t be stablished”.

I removed data/memory cache from safari on my device iphone and it’s still not opening the page.

Does anyone know what could be the reason and how to fix it?

Thank you in advance.
