Why does Chrome show a non-secure alert when redirecting to my thank-you page after form submission?

I received an alert from a customer who submitted this form: https://form.jotform.com/61035144538148 saying that he got a "non-secure" alert from Chrome when he clicked submit. 

I was able to recreate the same alert in a private window: 

It looks as though the thank you page URL is what is showing as non-secure, and Chrome doesn't even enable the visitor to override and go to the page anyway. I don't know why this is since the external page URL have embedded in the Thank You preferences for all my forms have the  https:// prefix the pages on my site are definitely secure. 

Can you please look into this? I am concerned we may lose business as a result of this issue. 

As far as I can tell, your page does not have an SSL certificate.  When you attempt to load your page from an https:// link, the security error shows that you do not have a current SSL certificate.  This is true when loading your thank you page.

For example, if you load your page from this URL, you will get the same error:

https://colorservicesllc.com/film-processing-order-form

However, if you load it from the non-https link, you will not:

http://colorservicesllc.com/film-processing-order-form

This is the same for your thank you page.  Change the URL from https to http and the error should no longer be present.
