Cisco Catalyst 9300 Web GUI - https not working

[roger perkin]

I have setup a stack of 3 x Cisco Catalyst 9300's 

Switches are operational and fully manged via SSH 

I was going to look at the GUI so enabled 

ip http secure-server 

however when I connect to https://<switch ip>/webui it fails 

This Site cannot provide a secure connection 

<switch ip> uses and unsupported protocol. 

This is the same for Chrome, Firefox and IE 

Disabled secure-server and was able to access the switch via http, but now http://<switch ip>/webui is redirecting me to https:// then failing? 

Any ideas anyone?

can you provide show version and make sure you configured below config and also username and password.

ip http server
ip http authentication local
ip http secure-server

Thanks for this, however my situation is the switches are up and running and being managed by SSH

If I disable secure server I can manage via http for a bit
