Could not verify a secure login

Hello,
after installing the demo APP I get this message

Could not verify a secure login

When I go back to my test shop Admin, I can see the App is installed. When I open the Demo App, I get the Error
7a548b94.ngrok.io has refused the connection

I started with NGROK with https

What do I have to do now?

Did you try to setup your app with https? like your finalize callback? Because I am not sure how to do that myself.

Can you give me all the steps that you have done to get to this point?

Hi,
for me is a similar error

I installed a Demo on Ubuntu Server with NGINX and craeted https certificate. After install via Shopify App frontend, I get the Error returned Could not verify a secure login

In Shopify Development I have one URL in Whitelisted redirection URL(s)
https://shopifyorders.my_domain_name/shopify/finalize/

And when I go to the teststore, I can also see the App, but I cant open. I get the Error shopifyorders.my_domain_name refused the connection

Do you have some extra hints to try out the Demo?
