Sangfor NGAF for VPN problems

addimasqi Lv2Posted 20 May 2020 16:57

I have some problems with the SSL VPN connection.  Sometimes when the client/user login SSL VPN on internet explorer, the browser showed this message, and sometimes the problems solved without any changes on the client and/or server-side.

error message

error message

Can anyone give me a guide about how to check this problem on the NGAF or the client?
FYI: The internet connection on the client-side and server-side is normal.

Start> Run> type in REGEDIT and hit Enter.

By clicking in the [+} drill down to
HKEY_CURRENT_USER  >  Software  >  Microsoft  >  Internet Explorer > Main

With Main selected in the left pane, right-click in the right pane and choose New> DWORD (32-bit)

Name the new DWORD Value TabProcGrowth then right-click it and set the value to 1.

If TabProcGrowth already exists (you didn't have to create it) just change the value from 0 to 1.

Try this on client system, may be it resolve your issue.
