I created a .Net Core 3.1 MVC application that is using induvial user accounts as authentication. I deployed the site to IIS, which works. However when I tried to log in with an account I know that works, the login does not succeed, and I am directed back the default route of the application. No error messages or log entries that I can find. The application pool is set up for non managed code, and is running under an account that has dbo rights to the database. Any thoughts as to what the issue might be?
Reboot has fixed the issue. I had installed the .Net core run times on the server, so prehaps a restart was needed.
