Netscaler VPN disconnects automatically

Recommended Posts

Netscaler Version 12.1 52.15

Symantec end Point Protection 14.2


VPN tunnel shows as established however its getting disconnected in 15-20 seconds.


Tried by uninstalling SEP features one by one with no luck.


The only solution so far identified is to uninstall SEP completely from devices which is not a solution. Any one faced similar issues? Any recommendation on exceptions available from Citrix on exceptions.  Tried below articles with no luck.

(If you haven't done so already) Can you enable debug logging for the NetScaler Gateway plugin and provide a sanitized copy of the log file for analysis here (or review it yourself and post follow-up questions based on your findings)?

There is a lot of good information in those logs that I believe would be helpful to you.

Please take a look at the following Symantec article (updated 08-06-2019):


https://support.symantec.com/us/en/article.tech255018.html - Bypass Endpoint Protection Web Traffic Redirection using LPSFlags.exe



Some 3rd party applications, such as SSL VPN clients do not support connecting though a loopback proxy. This document provides information on using LPSFlags.exe to add a list of one or more addresses to the proxy.pac file hosted by the Symantec Endpoint Protection (SEP) client Web Traffic Redirection (WTR) Local Proxy Service (LPS).


The article above was referenced in this Symantec article:
