If the error is observed on the specific application users due to inactive sessions, then you can relate the problem with the authentication timeout value specified in the access group.
Also from the screenshot, I could see that you are using PRWebLDAP1 (custom auth service), if your Auth service's custom tab uses checkbox "Use PegaRULES Timeout" then it considers the above authentication value.
If you guys are not using pxSessionTimer (custom) and above checkbox is selected, then the access group is the only place you specify timeout values.
