[Herman2022]

Hi, we setup foreign-anchor wireless network in our environment, but can't access anchor wlc mgmt IP via https, what is the possible cause? the engr who setup this wireless network already left. Now can still access anchor wlc via ssh, how to check whether https is enabled via cli? can someone please advise, thanks in advance. The wireless controller model is 5520.

Can I have the output of 'show network summary' and 'show sysinfo' please.

what exactly do you get? HTTPS timeout, or certificate warning?

check running config for 

    config network secureweb enable

just FYI if its not and u need to enable it it will need a reboot I believe

Anchor WLC is usually in DMZ of firewall so be mindful of that and make sure ports are allowed for services you are trying to access. via ssh run this command "show network summary" and confirm if you have these 2 services enabled

Web Mode.................................... Enable
Secure Web Mode............................. Enable

if its disabled, the enable them

config network secureweb enable

config network secureweb enable (this may require a reboot to take effect) 

if enabled, then try different browser, incognito mode, check your firewall rules. Also make sure you are not on wireless network while trying to access controller via GUI

Thanks @Haydn Andrews @Saikat Nandy @Saikat Nandy ! I found the root cause, it was blocked by the firewall. As you mentioned, anchor wlc is deployed in firewall dmz zone.  Thanks a lot for your advice!
