iis - Infinite redirect with identity server v3 as a middleware for ASP.NET MVC application -

i using identity server v3 owin middlerware asp.net mvc application. on production server getting infinite loop when user trying login.

after user authenticated, can see request redirected app , redirected identity server , loop continues.

this happens on prod server when trying host application inside "default web site". default web site using default ports http , https. if host application separate website or application inside website, works fine.

my default web site has applications configured use both classic , integrated pipeline modes. tried replicate scenario make sure not missing , have no problems.

i have verified make sure other identity server configurations correct. can throw idea on else can verify?

please try downgrading microsoft.owin.security.openidconnect 3.0.1 3.0.0.

edit:

an other reason, can stucked authorize 401. if so, link can better: why authorizeattribute redirect login page authentication , authorization failures?
