Grafana Screens are automatically logout

I have changed the grafana.ini file for auto logout grafana LCD Screens. But then also still Screens are getting logout frequently. I have shared the configuration as bellows:
login_maximum_inactive_lifetime_duration = 6M
login_maximum_inactive_lifetime_days = 90d
login_maximum_lifetime_duration = 90d
token_rotation_interval_minutes = 131400

Please suggest some advice that I can solve that Issues.
