If your upstream host is HTTPS, and you're not using forward auth, you need to access the outpost over HTTPS too.

# Logging out
Login is done automatically when you visit the domain without a valid cookie.
When using single-application mode, navigate to `app.domain.tld/akprox/sign_out`.
When using domain-level mode, navigate to `auth.domain.tld/akprox/sign_out`, where auth.domain.tld is the external host configured for the provider.
To log out, navigate to `/akprox/sign_out`.
