Troubleshooting Tip: How to avoid capture portal issues after a certificate change

Captive portals are usually secured behind a SSL certificate. Issues may occur when this certificate is changed. The cache could be wrong, or redirection after authentication might not work.

The following actions can be taken to fix this issue:

Clear sessions bound to the captive portal policy:

diagnose sys session filter policy <id>
diagnose sys session clear

Clear authenticated users bound to the captive policy:

diagnose firewall auth filter policy <id>
diagnose firewall auth clear

Clear the cache on the client machine:

On a Windows machine, press the Windows Key and R, then enter 'cmd' and press enter. In the command prompt that appears, enter the following:

certutil -urlcache * delete

Also in a command prompt, enter the following:

inetcpl.cpl

Navigate to the Content tab -> Clear SSL state.
