STS/IDP sesstion timeout after 10 minutes

Question

Hi

We have multiple IDP/STS (AD, Inhouse-IDP & Identity server) federated with ADFS 4.0 (on-premises ).
A user selects an IDP/STS from landing page list in ADFS server and redirected to there respective IDP page.
Now the user do nothing for 10 min in the IDP.
Exactly after 10 min the user enters there credentials and redirects to ADFS for federation token, but get error.
But when the user login in before 10 min it works, this is happening in all IDP.
Can some please help me understand what's going on?

Thanks
Anand
