Authentication failed captive portal

[Oblagonte]

Hi Expert,

We got error message "Invalid username or password" when try login to Captive Portal and affected a lot users.

There is no changes made and it is working last 2 days.

I look into Solved: LIVEcommunity - captive portal authentication failed LDAP - LIVEcommunity - 32582 (paloalton... but never try yet. 

Is there anything else we need to check and verify?

What does your logging say when the users fail to authenticate? Look at the "portal-auth" events in:

Monitor -> Logs -> GlobalProtect
