trying to connect aws share services landing zone. I installed cli from given command in aws cli documentation for windows. using gitbash to connect this. what is this error and what is this url given? any kind of additional access I want for this?

I have configured SSL for ELB with a custom domain using AWS ACM. Some browsers access domain that have a notification to choose SSL cert as image

I’ve created my own CA and I’ve generated a certificate with the template Web Server. I want to use in an application with tomcat. I load the pfx certificate in my Tomcat but when I’m trying to load the URL in the client it says me:

We’re young start up developing our software,
We’re about to launch, but need to secure our code.
Is ther anyone who can sign the code for us for a reasonable price?
