I have different VPN connections on my desctop Windows 10 Pro ver. 2004 (assembly 19041.1110).

All was good, but yesterday all VPN stoped work (all coonections was created with standart Windows utility, and I didn't update windows last month, then problem is not in OS). Picture with mistake (in Russian)
Pic. 1. Mistake of connection

url of Pic.1 (https://drive.google.com/file/d/14pdBO2zo9XNiBdMeEkc85W-gFJR5M0P7/view?usp=sharing)

I checked all configuration of Internet providers (I use 2 different Internet Providers), but no effect. I have a mistake on connections and mistake is same for  different types of VPN (pptp, l2tp/ipsec).

VPN works only if the antivirus is suspended (pictures with suspended Avast and with good connection)
Pic. 2 Avast was stoped

Pic. 3. Good VPN-connection

I have Avast Premium Security 21.6.2474 (assembly 21.6.6446.682), interface ver. 1.0.657

How to configure Avast for normal work with windows VPN?

Hi,

Could you temporarily disable the firewall and see if that makes a difference.
If it does, once connected to the VPN, open Avast Premium Security - go to > Protection > Firewall > under "Firewall Profile" set current networks to "Private Network"
