Hello,

I’ve installed A10 Control Lite Edition using .iso file, i have access over the CLI but can’t connect to the GUI interface. No service is running on TCP/443.

Any ideas?  
Thanks

Hi Radumihai,

Make sure you are using the floating IP to access the GUI (not the physical IP which is utilized to access the CLI)
