I recently had a very similar problem with VS 2019 and IIS Epress. I tried to change the http to https so that I could use ADFS. (Msg : This site is unreachable localhost does not allow connection).

After a little more research, I tried to switch the 'Require SSL' property from true to false and back to true. This triggered an update to the applicationhost.config file (... . Vs \ ProjectName \ config \ applicationhost.config) that created a new SSL binding with a new port number for the https protocol. So, I modified all the links with the proposed new port (in the web property of the project, the config file and the ADFS config) and it works. Conclusion, it is not necessary that the http port is the same as https same for the same site.
