* Fix PermissionError when importing http.server
Instead of crashing, now it'll just not start the server. This means that you won't be able to receive the response from the log-in so you won't be able to log in. The browser gives an error that it can't find the page on localhost. But at least it doesn't crash.

Attempt to fix the typing issue with MyPy. I can't run this locally so the CI server will have to tell me if this fixed it.
