Hi,

Are you sure that the https and ssh are enabled on your WLC?
Mangemetn -> HTTP-HTTPS.

If it is enabled then you better consider testing from different browsers and different clients.

It could be problem with the browser or the client you are using so you better eliminate this.

You also need to check devices in path between your device and WLC and make sure that there are no ACLs or so that drops the traffic.

HTH.

just a wild guess

check out if you have some proxy configured for the browser

check with another browser

Dear Amjad,

Thanks

Oh. sorry. I just noticed you metnioned this already in the first topic.

Then, I think we have a few steps need to be followed:
- Make sure it is not a browser's problem. (test more than one browser).

- Make sure it is not a client problem. (test more than one client).

- If above tested, you can simply collect sniffer trace on WLC port to make sure if the https traffic reach from the client or not. if not (and this is what I suspect) then search where the traffic is being dropped in the internal network and fix that. If it reaches WLC then the problem could probably be with the WLC and your first check then is to reboot WLC and check if it is fixed. if not you may need probably to open a TAC case
I worked with a user a time ago where he had a similar issue. But (if I remember correctly) it was fixed when the user resetted the WLC to default config. the problem was the use is not able to use GUI of the WLC (either HTTP or HTTPS).

Hope you'll catch the cause soon.

Dear Surendra,

after enable mgmt-via-dynamic-interface, from my pc (ip add 192.168.24.20/24), i can connect to dynamic interface (ip add: 192.168.24.200) but cannot connect to management interface (ip add: 192.168.255.200).

i think enable mgmt-via-dynamic-interface is not secure and i don't know how to manage WCL because i configure dynamic-interface for all vlan? shoud i manage WCL from the Service port or create a new vlan and manage WCL from this vlan.

thanks for your support!

I had cashed information on my firefox browser. Tried from the chrome and it opened. Closed firefox and re-launched it and I was able to access the controller once again.
Thanks for the help!
