Issue
I am trying to publish the application (blazor WebAssembly with individual authentication and asp.net core hosted) to a linux server, but it gives me an error,
I tried to add a certificate and a few startup options, but it did not help.

Solution
Your Linux target host is already has a process that is listening on port 443
Use something like netstat to see what it might be
