LG V20 H990DS MODEL PUBLIC WI-FI CONNECTION ISSUE

I'm a newbie here, just want some helpful tips regarding my new purchase Android phone LG V20.

There's no problem in all apps thru public Wi-fi connection in my workplace, the only issue is when i try to check the software updates, when i go to settings, about phone, LG software update, i got an error message;

"Could not connect to Update-server.
Please check network connection and try again."

Tried it several times but i failed

I don't know whats the latest security patch available,...
