"Unable to add accessory Accessory is not reachable" error in Home App
I have been trying to add my Samsung TV to the home add on my iphone and consistently get the error:
Unable to Add Accessory
Accessory is not reachable

I am running:

Node.js Version | v14.16.0
Npm Version | v6.14.11
homebridge-samsung-tizen v4.4.1

I have paired the TV to HomeBridge and when I click on the TV in the Accessories page I can turn off and back on the TV.  

The TV portion of the config.json:
{
            "app_list": true,
            "devices": [
                {
                    "name": "Family Room TV",
                    "ip": "correct IP Address",
                    "mac": "correct MAC",
                    "uuid": "A1"
                }
            ],
            "platform": "SamsungTizen"
        }
In the logs I see:
Preparing Advertiser for 'Family Room TV 077B' using bonjour-hap backend!
Starting to advertise 'Family Room TV 077B' using bonjour-hap backend!
[3/22/2021, 10:40:12 AM] Family Room TV 077B is running on port 46067.
[3/22/2021, 10:40:12 AM] Please add [Family Room TV 077B] manually in Home app. Setup Code: Setup Code

I have noticed that the setup code listed in the "Please add ..." line is the same setup code as for my HomeBridge.

I have many other devices working successfully in this homebridge and, as I stated above, from the accessories page in the HomeBridge web app I can turn the TV off and on so the connection from the homebridge to the TV seems to be working.  Its just getting the TV added to the Home App that is the problem. I have reviewed all of the closed issues concerning being unable to add the TV to the Home App but they mostly seem to hinge on adding "UUID": "A1" to the config but as you can see I already have that.  Any other ideas as to what's going on here?  Do I need to open a port in my firewall for the TV plugin?  I see it's running on 46067 and I have not had to open any other ports specifically for plugins but that port is definitely not open in my firewall.  

I have also checked my Samsung TV and I am up to date on firmware and I also turned on the ability to control the TV via IP and Power On with Mobile is also enabled.  

Thanks in advance for your time and help here!
