Exception thrown in state 'DisplayUsernamePasswordPage' of flow 'authn/Password'

[Losen, Stephen C (scl)]

Hi Marco,

Looks like the browser (or an intervening proxy, firewall, or load balancer) is dropping/closing the connection, so then the IDP cannot write the login page. I don't think this indicates a problem on the IDP.

Hello,

we are running Shibboleth IdP 3.3.3.

We are getting a lot of this error in idp-warn.log:

2019-01-15 00:00:09,588 - ERROR [org.springframework.webflow.execution.FlowExecutionException:76] -

Do you have any suggestion ?

Thank you very much.

Marco
