Good Day everyone!

I just want some helpful tips regarding my new purchase Android phone LG V20.

There's no problem in all apps connecting thru our company public wi-fi on this handset, 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, but my current security patch was way back November 2016 last year.

Any suggestion regarding this issue is much appreciated.

Thank you and waiting for some bright ideas from you folks☺!
