`HttpClient` disposed after two authorization attempts

[hburn7]

When two authorization attempts are made, the web server refuses to authorize the second one due to the HttpClient being disposed. The only fix is to restart the API (which then only allows one authorization through). To reproduce on local, login on otr-web (locally), clear cookies for localhost, then login again. This could be due to the RequestLoggingMiddleware but I have no idea.

The following error is displayed:
