FortiClient VPN disconnect occasionally during remote session

Hello,

Very happy with the ForitClient VPN for the purpose of remote desktop to my office computer.

Lately, after updating the Client to version 7.0.1.0083 , I noticed that every time I leave my PC for few minutes (making me some coffee) when I return the VPN is disconnected. This is something new that didn't occur while using the previous version.

I attach a logfile with few occurrences of disconnection.

 

Basically what I see in the log file is:

10/1/2021 10:17:33 AM error sslvpn FortiSslvpn: 36320: error: poll_send_ssl ->SSL_get_error(): 5, try:1 10/1/2021 10:17:33 AM error sslvpn FortiSslvpn: 36320: error: poll_send_ssl -> [style="background-color: #ffff00;"]WSAGetLastError():2745[/style], try:1 10/1/2021 10:17:33 AM error sslvpn FortiSslvpn: 36320: error: poll_send_ssl ->data size: 51, try:1 10/1/2021 10:17:33 AM error sslvpn FortiSslvpn: 36320: [handle_driver_read_event]: error: poll_send 10/1/2021 10:17:35 AM info sslvpn FortiSslvpn: 26580: Ras: connection to fortissl terminated

 

Searched for this: WSAGetLastError():2745  and found this in FORTINET:

 

FortiClients can sometimes have connection issues with SSLVPN. This sometimes includes error messages as follows:

Error    VPN    FortiSslvpn: 2148: error: poll_send_ssl -> WSAGetLastError():2745, try:1 Error    VPN    FortiSslvpn: 10908: error: poll_recv_ssl -> WSAGetLastError():2746

These errors are Windows Socket event errors, expressed in hexadeximal format. WSAGetLastError():2745, is the equivalent of error code 10053.

 

And the error code 10053 in Windows socket error codes list:

 

WSAECONNABORTED10053Software caused connection abort.An established connection was aborted by the software in your host computer, possibly due to a data transmission time-out or protocol error.

 

So, it seems like something in my Host computer that disconnect the connection.

What should I look for? Any idea? 

 

Thanks for your help,
