This is especially true with the use of SSL VPNs. These values should be set to fit the needs of the company and its end users. By default, VPN software might shut down a connection that has been idle for as little as 10 minutes, which might be too short for many users. One of the first settings to check is the VPN timeout setting itself. Once outside causes have been ruled out, it's time to check the settings and software for the remote user. If the vendor ends up being the cause, it might be time to change the VPN server or DNS server. This means checking that the VPN server being used is responding properly and that the DNS server used by the VPN vendor doesn't have any issues. If the user's internet connection isn't the issue, the next step is to ensure the VPN vendor isn't the root of the problem. If the user can connect via the wired LAN without any issues but has an issue periodically with the Wi-Fi or WLAN, start troubleshooting the agent logs and the origin of the logon attempts with an eye toward wireless-related issues. The majority of users connect via wireless LAN (WLAN) or Wi-Fi, and although it is becoming rarer for VPN software to lose connection due to poor Wi-Fi signal strength, it is a potential cause. If users are allowed to connect to the VPN from anywhere except a specific location, such as their local coffee shop, it could be that the internet connection at that location is blocking VPN access.Īnother way to determine the root cause of the VPN issue is to ask the user to connect to the VPN using a wired connection. Assess the userįirst, determine the user's location. When troubleshooting VPN session timeout or lockout issues, it's critical to isolate the problem to ensure faster and easier remediation.
