WLC 5520 Web GUI stopped working

[thasleem27]

Dears,

WLC 5520 is running with code 8.2 and we are facing using while login into the web GUI.

The browsers asks for authentication, but it doesnt take inside the GUI after entering the credentials.

CLI works fine and below are configured on WLC for GUI.

Web mode - Disabled

Secure web - Enabled

Advance secure web mode - Disabled

A reboot of WLC may resolve the issue but is there any workaround without going for a reboot or downtime?

Regards,

Thasleem

I've not experienced this issue but have you tried disabling and enabling secure web?

config network secureweb enable

The only other thing I can think of is cpu acls, do you have any configured?

Thanks for your reply.

Disabling or enabling network secureweb needs reboot to effect the change.

There are no cpu acls configured

Thanks,

Have you had a look at the release notes for the release you're running? There may alredy be a bug for this.

There is a bug affecting 8.2 that makes the web gui unresponsive and it has a workaround:
