I have connected LS server from my application, for us it's working fine without any issue. One of my client checked in Singapore and he said not working, while I checked through any desk by developer tool lsClient connection not getting establish. Connection refused issue comes. This only comes their system connected with their VPN, while I connect another network this is working fine. Whether I need to do any extra work for VPN servers. Please help on this issue.
