I am writing to you because in the company where I work we are having a problem while using Global Protect, some of my colleagues are no longer able to connect and receive the error you see below:

what could be the problem?

Many thanks for your feedback.

it could just be that they cannot see the portal at cosbppan01.net.americas.agilent.com.

what happens when they browse to https;//cosbppan01.net.americas.agilent.com

do they see the login page?

@Agilent8810,

You are failing the pre-login. So as @Mick_Ball mentioned it could be they are simply now unable to connect to the portal, or the portal configuration has updated breaking the pre-login process.
