Hi,
This is because you've restricted access to HTTP / HTTPS traffic to vlan.1 and fe-0/0/0.0
set system services web-management http interface vlan.1 set system services web-management https system-generated-certificate set system services web-management https interface vlan.1 set system services web-management https interface fe-0/0/0.0
Removing thos commands should give you access to webui through the st0 interface .
