UTM Parameters Stripped - .HT Access Issue

https://complystream.com/managing-an-effective-aml-compliance-program-2-day-in-person-seminar-000000126-sem.html?utm_campaign=Mailer&utm_content=AMLSEM-Apr9&utm_source=WebG

The aforementioned URL works fine with the UTM parameters intact.


However, when we remove https://; the page gets resolved to -
https://complystream.com/managing-an-effective-aml-compliance-program-2-day-in-person-seminar-000000126-sem.html

and the UTM parameters are stripped off.

By default, all http pages are supposed to be redirected to use https://


Can someone please assist in fixing this issue.
Where someone can type in a link without https; and the site will direct them to the https counterpart without stripping the utm parameters.

We use Magento.
