ZyWALL Secuextender VPN SSL - Can't get authentication token(1)
Hi,
Several of the PCs can no longer connect to the VPN. The SecuExtender.log shows the following error "Can't get authentication token (1)" and SecuExtenderHelper shows this error: "[2021/10/04 11:34:50] [SecuExtender Helper] Failed to read from client (2): 109, 0 "

From computers outside the network I connect without problems
I appreciate your help

What is your version of SecuExtender SSL VPN Client? Do you upgrade to the latest Zyxel firewall firmware? I use SecuExtender SSL VPN with 4.0.4.0 version can establish SSL VPN connection with my USG devices(with V4.65p1) without any problem.
BTW, maybe you can refer to below discussions that are related to SSL VPN. Hope it can help you .
