Branding Question

[celsius-233]

I created a brand but it doesn't seem to work. My setup is that I have Authentik running on my TrueNAS server on port 30141 for https. I have a DNS record pointing to the IP of this server for the url authentik.carport.lan. I have my own cert assigned to this URL and added to the brand as the web cert. When I navigate to https://authentik.carport.lan:30141 it still presents me with the default Authentik self-signed cert and not the one I assigned; so I'm assuming that the branding isn't working. Is there an issue with not having a standard port that could be messing up the branding? Thanks and any pointers is much appreciated.
