Failed to pre-login to the portal Error 0

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:

it could just be that they cannot see the portal at


what happens when they browse to https;//



do they see the login page?

You are failing the pre-login. So as @MickBall 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.
