Have an issue with Sitecore Horizon where I have installed it with a self-signed cert and now I'm swapping it for a real certificate and a proper domain. I did the same for Identity server and it was fine however when I try this for Horizon it seems to give me this error.
I've updated IIS with the custom domain and I am using a wildcard certificate which is a client/server cert (works for Identity and XConnect). Spinning up Horizon seems to use Network Service on the App Pool which i've given Read permission on my custom Cert. I've also tested giving "Everyone" access and it made no difference.
Just wondering if anyone can think of something I may have missed here?
