Login To Fortigate Firewall Disconnects In Less Than A Minute

I am using a public internet to login as administrator through the wan interface.

Although wan interface is using a dynamic ip, I dont think the ip changes so fast.

After I login to the firewall, after less than 1 minute, it will jump back out to the login page.

What can be the cause of this issue?

Hello @BusinessUser 

As I understand that you are facing issues with the Firewall getting logged out in less than a minute.
Kindly check the Idle timeout settings from the below document link.
https://docs.fortinet.com/document/fortigate/7.4.0/administration-guide/215451/setting-the-idle-time...

1. Go to System > Settings.
2. In the Administration Settings section, set the Idle timeout to up to 480 minutes.
3. Click Apply.

Hope the above doc. link would be helpful for you.

Thanks,

Actually the firewall will reject unsecured connection from a public wifi.

But I dont know how to fix it

Hello @BusinessUser 

If you find yourself unable to log in from a public network, it's probable that you have trusted hosts

or a local-in-policy in effect. On the other hand, if you can log in but get logged out from the Fortigate after a certain period, this issue is likely linked to the Idle timeout setting.

I am sharing the link for trusted hosts and for Local-in-policy

I dont know why but the issue only happens when i use a free public wifi.

For secured connections it is ok.

Anyway it is the public wifi and not fortigate issue

Hi there,

Have you tried incognito tab or maybe a different browser?
