Re-authenticate to external identity provider

[Akash1842]

I initiate the workflow from postman (OAuth 2.0). I am using duende identity service and through that I am redirecting to external identity provider. Login is successful and it return to authorization service. Consent screen open for scope but when user submit consent after expiration of cookie then user not able to re-login again. I can see it call Account/Login method after cookie expiration but below method return null.

var parsedRequest = await _returnUrlParser.ParseAsync(returnUrl);

Workflow:
Postman -> Duende Auth Service -> Idp login - Callback method in Duende Auth Service -> Consent page.

Cookie setting:

options.Authentication.CookieLifetime = new TimeSpan(0, 0, 60);

Is there any way to re-authenticate user again ?

Could you share log entries from IdentityServer when this issue occurs? That would help us in seeing more about what's (not) happening.

I would try to increase the cookie lifetime a bit, because the current configuration will expire the authentication cookie after 1 minute (60 seconds). The default configuration sets the lifetime to 10 hours and disables sliding expiration.
If you want to set a lower lifetime, you can also use one of the TimeSpan.FromXYZ factory methods:

options.Authentication.CookieLifetime = TimeSpan.FromMinutes(10);

As of now I increased the cookie life time. Ok will share that log soon but meanwhile here is the URL for reference:

Below URL will see when cookie is expired and it calls the account/login method.
/consent?returnUrl=/connect/authorize/callback?cust=fpdb_CNG_261_INFERNO010120250348&response_type=code&client_id=1a8adfe8-aba9-42fd-90e4-8fa461d82d3a&scope=fhirUser&redirect_uri=https://inferno726.dg-testlab.com/custom/smart/redirect&code_challenge=lVxSIbMdOaCsQ9XS6LG81LO5XiEhjWXmGjoS9SBI53M&code_challenge_method=S256

I know that parseAync will return null but need to figured out how to perform complete workflow again after cookie is expired.
