WebUi access for catalyst 3650

cbgrape
Level 1
Level 1

I am trying to access the WEB UI but it is giving me error:

ERR_SSL_VERSION_OR_CIPHER_MISMATCH

The client and server don't support a common SSL protocol version or cipher suite.

I am using client with Windows 2019 server OS.. 

Chrome Version 123.0.6312.58 .   and Internet Explorer 1809

on Cisco Switch side the error message is:

%WEBSERVER-5-CONNECTION_FAILED: Switch 1 R0/0: nginx: connection failed from host 10.250.0.12 - Cipher Mismatch/No shared cipher

Please advise, thanks

-- Each morning when I wake up and look into the mirror I always say ' Why am I so brilliant ? '
    When the mirror will then always repond to me with ' The only thing that exceeds your brilliance is your beauty! '

it has Cisco IOS XE Software, Version 16.12.04

 

  - Does it work for you from a standard Windows 10 PC for instance, because if you are on a Windows Server OS , sometimes enforced policies may lead to  extra restrictions (?)

Hi Marce

it's giving same error when i am using Windows 10PC.  

using chrome : i am getting the following

 

This site can’t provide a secure connection10.250.0.254 uses an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
Unsupported protocol
The client and server don't support a common SSL protocol version or cipher suite.

using IE:

Can’t connect securely to this page

This might be because the site uses outdated or unsafe TLS security settings. If this keeps happening, try contacting the website’s owner.

Your TLS security settings aren’t set to the defaults, which could also be causing this error.

message on switch:

5 11:29:59.037: %WEBSERVER-5-CONNECTION_FAILED: Switch 1 R0/0: nginx: connection failed from host 10.250.0.1 - Cipher Mismatch/No shared cipher

 

 - At a first glance available ciphers between the browser and switch do not match, check for instance  TLSv1.1 & TLSv1.2 settings in the browser. For the 3650 use   nmap --script ssl-enum-ciphers <3650-ip-address>.  or show  ip http server all 
                     Check for potential influences of stuff like firewalls , proxies , AV software

I check the browser:  TLS1.2 and TLS1.1 are enabled.  

i used the command show  ip http server all,  shows the following
