SSL VPN Problem

Hi, 

I'm having problems connecting the SSL VPN in only one user. All the other 15 users have no problems connecting. He gets the following information in the logs

    Which Zyxel device you are using? and its firmware version? Not sure if your SSL VPN numbers had reached the maximum value?

    I'm using a USG FLEX 100W   with the following Firmware version : V5.20(ABWC.0). I only get this error in one specific laptop even if a try to establish the VPN with users that are working fine in other laptops. So I believe that the problem has to be related with this specific laptop.  When I first installed the secuextender it worked, but after a few days I started having this error

    What is your SecuExtender SSL VPN client software version? your PC brand and its model name? and its OS version? Do you open the SecuExtender IPsec client on the PC at the same time? If so, please turn off IPsec client and only turn on SSL VPN client to see if it works?. BTW, you can turn off Anti-Virus software, firewall-related settings or other internet-related utility on your PC to see if it works?

    If it's a HP device, try to dissable the "HP LAN / WLAN / WWAN Switching UWP-Service"
