“Secure VPN connection terminated locally by the Client. Reason 412: The remote peer is no longer responding”

Questo errore è capitato diverse volte, la connessione sembra andare in timeout e si chiude.
Per risolverlo ho trovato questa procedura.

1. Delete the current VPN policy from the user’s VPN client
2. Using a text editor, open the .pcf policy file
3. Add the line “ForceKeepAlive=1” anywhere in the file along with the other parameters
4. Save the .pcf file and re-import it to the VPN client

NOTE: If the “ForceKeepAlive” line is already there but is set to “=0,” simply change it to “=1.”
