update error

hello, my friends.

I have update problem and need your help.

my win10 laptop installed 'bitdefender total security', and it got update error for days.

”update error... please check your internet connection and try again."

I tried update it with or without an VPN, all failed.

The weird thing is under the same WIFI network at my home, my macbook which installed 'bitdefender antivirus for mac' has no update problem, 'update completed successfully' evey 10 hours without VPN.
