The links in the email do not open

Your software
My Mautic version is: 5
My PHP version is: 8.1
My Database type and version is: mariadb 10

Your problem
My problem is:
After clicking on the links in the email sent, the opened page gives the error "not “secure” in the address bar and the target link does not open.

Also, I noticed that the generated tracking address is http instead of https

These errors are showing in the log:
nothing in the log!

You’ll need an SSL installed on your web server.

And most likely the origin of the issue:

1. Make sure to access your web app (Mautic) using the SSL.
2. Double check your “Setting >> Configuration >> System Settings >> Site URL”. It should be using the HTTPS:// in the URL.

Thanks
all of them were correct.
Now I redirected http://tracking.example.com to https://tracking.example.com in nginx block, and the problem was removed.
