topic Issues with Check Point Mobile VPN Reconnection after Initial Setup in SASE and Remote Access https://community.checkpoint.com/t5/SASE-and-Remote-Access/Issues-with-Check-Point-Mobile-VPN-Reconnection-after-Initial/m-p/276934#M14505 <P>Hello all,</P><P>I have configured my Quantum Spark 3920 gateway as a VPN server for remote clients. I am using Active Directory (AD) for authentication, and it is working correctly.</P><P>After installing the Check Point Mobile Application on a Windows machine, the site wizard appears to configure the first site. I enter my external IP, and the wizard identifies the gateway configuration perfectly.</P><P>When I use my credentials to connect, the client communicates with the gateway, authenticates successfully against the AD server, and the tunnel is established.</P><P>However, if I disconnect and try to reconnect, the connection fails. Interestingly, if I delete the site and recreate it, the connection works again for that single session.</P><P>Does anyone have any insight into what I might be missing or doing wrong? Any help would be appreciated.</P><P>Regards.</P><P>Rafael</P> Thu, 14 May 2026 16:33:48 GMT RafaelBohrer 2026-05-14T16:33:48Z Issues with Check Point Mobile VPN Reconnection after Initial Setup https://community.checkpoint.com/t5/SASE-and-Remote-Access/Issues-with-Check-Point-Mobile-VPN-Reconnection-after-Initial/m-p/276934#M14505 <P>Hello all,</P><P>I have configured my Quantum Spark 3920 gateway as a VPN server for remote clients.
