Avast premium bloqued Avast VPN

Hi,
since few days , I can’t use my avast VPN because when it is started, i don’t have internet access . I’m in a private connexion at home . When I disconnect the FW, the intenet connexion thrut VPN acces is OK . I have never change any rules of the FW .
Where is the probleme ?

Thanks

Finally I have found this problem myself . In the FW network tab, Secureline was not configured as a trusted site . After validation the internet acces does works thrut the VPN

Regards
