Cannot connect to Bitdefender server automatically. How to fix?
Every time I turn on my PC, the Bitdefender symbol is always gray (it's red before) showing that Services servers are not responding and communication failure. I have to click on it manually multiple times expecting it to connect to the server successfully. Most of the time it does, but it's really annoying.
Can someone please help? Thanks so much!
I'm running on Windows 10 64-bit, no VPN turned on.

If you are currently using the default DNS (Domain Name System) from your Internet provider, switch to a third-party DNS server that might be faster and reliable. Change the DNS server settings by following these steps. The instructions apply to all Windows versions.
Aggressive firewall settings (e.g. Windows firewall, 3rd party firewall software, router’s built-in firewall) can prevent Bitdefender from communicating with the activation server.
Turn off Windows Firewall using the method described in this Microsoft article.
If you are not sure if your router comes with a dedicated firewall or how to turn it off, please refer to its manual, contact the manufacturer or your Internet provider.
The Internet Explorer version present on your system could be outdated or corrupted. Some Windows components are directly related to Internet Explorer, and Bitdefender runs an Internet Explorer framework. Reset Internet Explorer settings to make sure it’s functional and up to date.
An outdated Network Adapter Driver can result in connection issues. Update your network adapter drivers for better performance. You can find more information on how to install the latest driver available for your network adapter in this article.
If you have followed all the above steps, but Bitdefender is still unable to connect to the server, there may be an issue with the way the network is configured. To correct it, please flush and reset the DNS by following the instructions below.
Open Command Prompt with administrator privileges: click the Windows Start ⊞ menu, type cmd then right-click the Command Prompt option in the search results and choose Run as administrator.
Type the following at the command prompt:
Type ipconfig /flushdns and then press Enter on the keyboard.
Type ipconfig /release and press Enter.
Type ipconfig /renew and press Enter.
Next, type netsh winsock reset and press Enter
Finally, type netsh int ip reset and press Enter.
Restart your computer afterwards.
Hope this helps,
