SSL VPN Disconnect Frequently

After deploying SSL VPN . A user get frequently auto disconnected and display "You have logged out The session has expired. Please log in again". in range time of 30 minutes.

I have configure the
"Disconnect user if inactivity period reaches for 360 minutes" , hence this is not the issue.

Do i need to create policy to allow my virtual ip to Resources and set is as allow?

Is there a way to look at the event which cause this issue? I have try look into Access logs>SSL VPN Logs , no event show me what causes it to disconnected.

can someone guide me?

If user is using FTP to access a POS system application within SSL VPN Network, will this degrade the sslvpn performance which cause high latency and also frequent sslvpn disconnect? Is this possible cause?

If a user is frequently getting auto-disconnected from the SSL VPN with the message "You have logged out. The session has expired. Please log in again," there are a few things you can check and troubleshoot:

Inactivity Timeout: You mentioned that you have configured the "Disconnect user if inactivity period reaches for 360 minutes," so this is likely not the cause of the frequent disconnections. However, double-check the inactivity timeout settings to ensure that it is not set to a lower value somewhere else in the configuration.

Resource Access Policy: It is possible that the virtual IP of the SSL VPN client needs to be explicitly allowed access to the resources it is trying to connect to. Check your resource access policies and ensure that the virtual IP of the SSL VPN client is included in the allowed list.

Event Logging and Analysis: To identify the specific events causing the disconnections, it is recommended to enable detailed event logging on the SSL VPN server. Check if there are specific log settings related to SSL VPN or user sessions that can provide more information about the disconnects. Look for logs related to session expiration, authentication failures, or any other relevant events.

SSL VPN Client Settings: Review the SSL VPN client settings to ensure that there are no specific session timeout configurations or settings that may be causing the disconnects.

Network Connectivity: Verify that there are no network connectivity issues between the SSL VPN client, SSL VPN server, and the resources being accessed. Network disruptions or intermittent connectivity problems can cause session drops.

SSL VPN Software/Firmware Updates: Check if there are any available software or firmware updates for the SSL VPN server or client. It's possible that a known issue or bug related to session management has been addressed in a newer version.

If the issue persists after checking these points, it may be necessary to engage the technical support of the SSL VPN vendor or consult their documentation for specific troubleshooting steps. They will be able to provide more accurate guidance based on the particular SSL VPN solution you are using.

There are a few possible reasons why a user might be getting frequently auto-disconnected and displayed with the message "You have logged out. The session has expired. Please log in again." within a range of 30 minutes:

    Session timeout: Most applications have a session timeout setting, which is the amount of time that a user can be idle before being automatically logged out. This is done to protect user security and prevent unauthorized access to accounts. If the user is frequently auto-disconnected, it is possible that the session timeout setting is too short.
    Network connectivity issues: If the user's network connection is unstable or intermittent, it can cause them to be disconnected from the application. This can happen even if the user is actively using the application.
    Application bugs or glitches: It is also possible that the application itself is experiencing bugs or glitches that are causing users to be auto-disconnected.
    Security settings: In some cases, the user's security settings, such as antivirus software or firewalls, may be blocking the application from maintaining a stable connection.

To troubleshoot this issue, you can try the following:

    Check the session timeout setting: Increase the session timeout setting to see if this resolves the issue.
    Check the user's network connection: Make sure that the user has a stable and reliable network connection.
    Update the application: Make sure that the user is running the latest version of the application.
    Disable any security software or firewalls that may be blocking the application.
    Contact the application developer: If you have tried all of the above and the issue persists, contact the application developer for support.

Here are some additional tips to help prevent users from being auto-disconnected:

    Encourage users to stay active in the application by regularly performing tasks such as clicking on buttons or entering text.
    If the user is going to be idle for an extended period of time, recommend that they log out of the application.
    Use a keep-alive connection to maintain a continuous connection between the user and the application.
    Monitor the application's logs for any errors or warnings that may be related to session timeouts or disconnections.

By following these tips, you can help to reduce the number of users who experience frequent auto-disconnections.

If you have configured the disconnect user if inactivity period reaches for 360 minutes, then the issue is likely not with the SSL VPN session timeout setting. One possibility is that the user's network connection is becoming unstable or dropping out periodically. This could be due to a number of factors, such as a problem with the user's ISP, router, or firewall.

Another possibility is that there is a problem with the SSL VPN client itself. The client may be outdated or corrupted, or there may be a conflict with another software program on the user's computer.

Finally, it is also possible that there is a problem with the SSL VPN server itself. The server may be overloaded or experiencing other technical difficulties.

To troubleshoot the issue, you can try the following:

• Ask the user to check their network connection and make sure that it is stable.
• Ask the user to try updating the SSL VPN client to the latest version.
• Ask the user to try disabling any other security software programs that they are running.
• Check the logs on the SSL VPN server to see if there are any errors or warnings.

  
  
  
  

To answer your specific question about creating a policy to allow your virtual IP to resources, this is not necessary. The SSL VPN client should already be configured to route traffic through the virtual IP. However, you may want to verify this by checking the SSL VPN client configuration.

Here are some additional troubleshooting tips:

• Ask the user to try connecting from a  different location. This will help you  to determine if the problem is with the user's network connection or  with the SSL VPN server.
• Ask the user to try connecting using a  different VPN protocol, such as OpenVPN or L2TP. This will help you to  determine if the problem is with the SSL VPN protocol or with the SSL  VPN server itself.
• If you are using a load balancer to  distribute traffic across multiple SSL VPN servers, try connecting to a  different server. This will help you to determine if the problem is with  one particular server or with all of the servers in the load balancer  pool.

  
  
  
  

In addressing the SSL VPN disconnect issue, it's crucial to conduct a comprehensive review of your system. Start by verifying the VPN server settings, ensuring there are no conflicting configurations and that session timeout settings align with your requirements. Additionally, inspect network devices such as firewalls, routers, and switches to rule out any session timeout conflicts. Take a close look at client-side VPN settings, checking for custom inactivity timers or intermittent network problems on client devices. Despite having examined SSL VPN logs, reevaluate them for any specific error messages or events preceding the disconnections. Increasing logging levels might provide more detailed insights. Delve into system logs on the VPN server to identify potential resource exhaustion issues or error messages coinciding with the disconnects. It's also prudent to enable debug or verbose logging on the VPN client side for a deeper understanding. Ensure all involved software and networking equipment are up-to-date, as software/firmware updates often resolve known issues. While creating specific policies for virtual IP access is essential, the disconnect problem might not be directly related. If all else fails, consider seeking assistance from your SSL VPN solution provider's support team or consulting a network security expert for a detailed analysis of your setup.

Consider reaching out to the vendor or manufacturer of the SSL VPN solution for further assistance. They may have specific troubleshooting steps or recommendations based on their product's configuration and behavior.

Monitor the system resources of the SSL VPN server, such as CPU and memory usage, to ensure they are not reaching their limits. Insufficient resources can lead to instability and session disruptions.

Verify that the SSL VPN solution is not experiencing any issues with its licensing or capacity. If the number of concurrent users exceeds the licensed limit, it could result in unexpected session terminations.

Check if there are any specific policies or rules that might be causing the frequent auto-disconnections. Review the configuration settings related to session timeouts, idle timeouts, or any other parameters that could be affecting the user's session duration.

Look for an option or field related to HTTP headers or client request headers.
