Working on setting up the IWA agent. When I setup the routing rule to use the IWA agent I get a 405 HTTP error. I've reinstalled the IWA agent a couple times and made sure that the settings for IIS match the Okta setup guide. Still unable toget SSO with IWA to work. Any ideas?

what happens when you go to https://servername.yourdomain.com/IWA in a browser? Is this a clean win 2016/2019 server, domain attached, only running IIS and the IWA agent?
Redirects to https://our-domain.okta.com/login/default.
New server (VM) for the IWA agent. Server 2019 with IIS and the IWA agent installed. Nothing else on the server.
