What is the issue or idea you have?

STF does not appear to be passing the state token to the Oauth2 provider (IBM Security Access Manager) when running "local" with a public IP

Please provide the steps to reproduce the issue.
Running an instance of STF local with a remote Nginx server doing HTTPS (configured per deployment guide)

1. Launch STF:

export STF_AUTH_OAUTH2_OAUTH_CLIENT_SECRET=XXXXXXX
export STF_AUTH_OAUTH2_OAUTH_CALLBACK_URL=https://XXXXXXX/auth/oauth/callback
export STF_AUTH_OAUTH2_OAUTH_USERINFO_URL=https://XXXXXXX/mga/sps/oauth/oauth20/introspect
export STF_AUTH_OAUTH2_OAUTH_SCOPE=openid email
export STF_AUTH_OAUTH2_OAUTH_CLIENT_ID=XXXXXXX
export STF_AUTH_OAUTH2_OAUTH_AUTHORIZATION_URL=https://XXXXXXX/mga/sps/oauth/oauth20/authorize
export STF_AUTH_OAUTH2_OAUTH_TOKEN_URL=https://XXXXXXX/mga/sps/oauth/oauth20/token

stf local --public-ip XXXXXXX --lock-rotation --auth-type oauth2

What is the expected behavior?

I'd expect the state token to be sent to the authentication provider

Do you see errors or warnings in the stf local output? If so, please paste them or the full log here.
