When I try to go to the IP on a browser Outside of Network, I get the "Connection is not Private" warning, then when I proceed it says page cannot be found. What am I missing here? Thank you.
Well it proves that you can at least access the login page, which is good!
Try appending /admin after the IP address. E.g:- "https://188.8.131.52/admin" - obviously replacing 184.108.40.206 with your IP address
If you already have ASDM installed then you don't need to open a web browser, you can just open ASDM set the IP address as the outside interface IP address and then login.
I only have ASDM installed on my domain controller. I was wanting to put ASDM on 2 laptops for remote users but am not able to access through browser as I mention earlier. I have tried just the https://ipaddress and also https://ipaddress/admin. Neither are working.
I did get the login screen to come up in Internet Explorer. It is asking for my login credentials, then tries to install AnyConnect VPN. Is this normal? Is it because I did not put admin after the IP Address?
ACLs are (generally speaking) for traffic going THROUGH the firewall - not traffic TO the firewall.
It's as @RJI said for allowing management traffic (which terminates on the firewall - i.e., TO the firewall).
