Can't access Web UI on Catalyst 9300L

Hello,

I'm currently trying to access the Web UI of my Catalyst 9300L switches. I can access the switches via SSH but not via web.
It simply won't load the site. Looks like port 80/443 is not open... Do I need to set some other settings to get it running?

There is currently only the management interface configured. No VLAN.

I enabled the Web UI via:

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

Output of show ip http server status shows:

cisco#show ip http server status

 Any tips to get this working?

connect the PC to management port and first try ping 

I can ping the switch and even connet via SSH, as already mentioned. The network itself is working.

in any browser enter 
http 
not 
https 

as I see the https is disable even if you enter ip http secure-server

I tried http only too.

ip http secure-server <<- remove this command
and 
check again with http only 

Tried this one too. No luck. I don't get it...

Hi,

Try a different browser.

HTH

I tried Edge, Chrome and Firefox. Also wget on Linux shell. It looks more like the switch is not offering HTTP/HTTPS. I get a network timeout. It's not a certificate or browser compatibility problem.

As I said: I can ping it and also connect to it via SSH.

Got it working. I put my computer into the same network like the management port. 
So it looks like there is some sort of network filtering active. How can I disable/configure this?

The next thing I noticed is that there are menues missing like "Configuration" in the Web UI. Can this be a permission thing?

what kind of missing, can you post exmaple :

as long as user have priv 15 you should be good.

I gave the user priv 15. Now I can access all menu entries. Thanks for the hint!

Any tips for the limit that I can only connect to the Web UI if I'm on the same network like the management port?
Haven't found any settings to change...
