Hi

FortiClient write this error log, when i use SqlServer Replication Merge for merge data from one server to another with FortiClient VPN on:

11/29/2018 8:20:55 PM Debug VPN FortiSslvpn: 17484: [SSL-OUT] size = 1400 11/29/2018 8:20:55 PM Debug VPN FortiSslvpn: 8440: error: poll_recv_ssl -> SSL_ERROR_SYSCALL error:WSAEWOULDBLOCK 11/29/2018 8:20:55 PM Debug VPN FortiSslvpn: 17484: [SSL-OUT] sent ------> 1400 11/29/2018 8:20:55 PM Debug VPN FortiSslvpn: 17484: [poll_read] pending 11/29/2018 8:20:55 PM Debug VPN FortiSslvpn: 17484: [tunnel_loop_read_driver] wait for adapter 11/29/2018 8:20:55 PM Debug VPN FortiSslvpn: 17484: [tunnel_loop_read_driver] adapter read event 11/29/2018 8:20:55 PM Debug VPN FortiSslvpn: 17484: handle_driver_read_event: in len:110 11/29/2018 8:20:55 PM Debug VPN FortiSslvpn: 17484: bytes sent:44105 bytes recvd:30458 [handle_driver_read_event] 11/29/2018 8:20:55 PM Debug VPN FortiSslvpn: 17484: hdlc_encode: out len:114 11/29/2018 8:20:55 PM Debug VPN FortiSslvpn: 17484: [from adapter] -----> 118

When the SqlMerge agent start, the ping on the cloud server is Request Timeout. The firewall on the 2 machines, are turn off.

Is possible that FortiClient block the Tcp channel?

I have attached the logs file.
