internet going down every 5 minutes when active authentication ?

Hi Mohammed Fouad,

Thank you for reaching out to the Community! 

What is the firmware version on your firewall? When you enable authentication, did you see traffic drooped by the firewall in the logs? 

Could you provide access_server logs from the firewall? 

Thanks,

Thank you for the replay 

My firmware version on the firewall is SFOS 17.5.3 MR-3

and when enable authentication the internet down only on the user laptop but on sfos everything is good and working fine ( Ping, VPN, .....  )

Best Regards

First of all, i would highly recommend to update to a newer version. 

Second, do you mean, you enabled STAS for authentication? 

Try to disable the Quarantine:
