Problem after update VPN Gateway -> TOR

i`am using Whonix 11 version after the next update Gateway, I am talking about the update which includes Tor Data folder on the desktop, we started having problems with VPN installed on the Gateway. The problem a little digging I realized that the problem of mutations both in the firewall settings should be applied.

###########################
## VPN-Firewall Settings ##
###########################
## Make sure Tor always connects through the VPN.
## Enable: 1
## Disable: 0
## DISABELD BY DEFAULT, because it requires a VPN provider.
VPN_FIREWALL=1

## IP address of the VPN server.
## Get the IP using: nslookup vpn-example-server.org
## Example: seattle.vpn.riseup.net
## Some providers provide multiple VPN servers.
## You can enter multiple IP addresses, separated by spaces.
VPN_SERVERS="IP"

## For OpenVPN.
VPN_INTERFACE=tun0

## Destinations you don not want routed through the VPN.
## 10.0.2.2/24: VirtualBox DHCP
LOCAL_NET="192.168.1.0/24 192.168.0.0/24 127.0.0.0/8 10.152.152.0/24 10.0.2.2/24"

after the upgrade began these settings:

this change is not currently in the documentation, please add, but that the problem did not end now connect to the VPN occurs normally, but occasionally at the VPN, the connection with the error:

Before the update did not have such problems, please help with the decision.

‘Occasionally’ doesn’t sound like Whonix could be the source of the
error. More likely a problem with the VPN provider or the ISP censoring
connections. The VPN related firewall code (iptables) hasn’t changed
between Whonix 11 and Whonix 12.
