Can't connect to WebUI of second instance of docker container

[kwatz]

I'm trying to run a second instance of radarr on my unraid machine. I went to Docker > Add Container > From Template > Radarr, then changed the port and renamed the container and the appdata folder "radarr4k". The port on the original radarr instance was 7878, and radarr4k is 7879. The one issue I have is when I go into the detailed editing screen for port number on radarr4k, it says container port is 7878, and I am unable to change it. The ip addresses shown in my docker hub are as follows:

radarr: 172.17.0.2:7878/TCP <-> \[my ip\]:7878

radarr4k: 172.17.0.9:7878/TCP <-> \[my ip\]:7879

Here are the settings for the radarr4k docker container including the detailed port screen (also attached):

docker settings 1
docker settings 2
detailed port settings
docker addresses/ports

When I attempt to connect via the WebUI for the new instance, it says it cannot connect. Having no such issues with the original instance. What am I doing wrong? Thanks for any advice.

I continue to have this same problem and can't figure it out. Did you ever find out how to solve this?
