Unable to access Web Interface

neilmac — Sun, 04 Jul 2021 02:33:09 GMT

I have a WS-3750 and I am unable to access the web interface of the controller.

I can ping and telnet, just no web. I have restarted the controller, still no joy.

Any ideas as to how to get it back ?

Many thanks,

Hello,

both are not wokring?

also please confirm that your browser not having proxy settings blocking this IP...

if not working , can you please attach the config of switch and WLC (show run-config)

Hi.

I can confirm, http and https both not working, there are no proxy settings or browser settings to stop access.

I will send config later as I am not on site right now and need to remote in.

If you have any ideas of anything I can check in the meantime please let me know.

Neil

Hello,

as we are sure that we can telnet then it is not connectivity issue...

please check the following:

1) show network summary. both HTTP/HTTPS enabled at WLC?

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

2) are you accessing WLC from client in same VLAN as managment interface?

if not please make sure that there is no ACL blocking port 80 / 443.

Best regards

Hello,

as they are enable.

are we accessing from client in same VLAN as WLC management?

can you please test from client in same VLAN?

do you have any ACL on these VLAN's? also is there any ACL /CPU ACL on the WLC?

if no success i would suggest sniffer on client , and on WLC port channel to check the HTTP(S) traffic.

does it reach WLC or not. and if WLC responsd to that .......

Kind regards

Yep, it's the same VLAN, nothing has changed, it previously used to work.
