@amirabasalinaghi Hello! This looks like a client side issue rather than a problem with the VPN setup scripts. There has been no recent updates to the setup scripts that could cause the SSH connection issue you described.

Please provide more information - how did you SSH to the VPN server after connecting to the VPN? i.e. Which IP did you use? If you used the server's internal VPN IP 192.168.42.1 for SSH, note that this IP is only valid when clients connect using IPsec/L2TP mode. The VPN server does NOT have an internal VPN IP when clients connect using IPsec/XAuth mode. In this case, what you described is normal, and as an alternative you can instead use the VPN server's public IP for SSH.
