@novajones001 - You’re going to have to provide a lot more detail.

It that IP address the IP address of your mirror?
Are you trying to view the content or configure the mirror?

If you’re trying to view the content, then open your web browser and enter http://192.168.1.4:8080 in the address bar.

If you’re trying to configure your mirror, then you need to SSH into that IP address with an SSH client. If you’re using Ubuntu, Debian or other flavor of Unix, you can just type ssh pi@172.168.1.4 at the command prompt. It will ask you for a password, which by default is raspberry.

If you’re using Windows 10, you have to open PowerShell and then type that command. (Did everyone know that PowerShell has SSH capability? I did not.) You’ll still have to enter the password.

Let us know how it goes.
