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)

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”
