Zyxel Secuextender Disconnects after 1 Minute 21 Seconds

Hi all, new user here trying to get an answer to this question.

I am using the latest version of SecuExtender (Found here:https://www.zyxel.com/global/en/support/download?model=secuextender-vpn-client)
Software Version SSL_VPN_Client_4.0.4.0

I have tried to reinstall, repair, completely uninstall and reinstall, to no avail. I have read about updating firmware, but through the app there is no firmware to update to my knowledge.

    I concur with PeterUK's conclusion. The SecuExtender is only a VPN connection client to open a VPN connection through the ZyXeL firewall you use to protect your network. It would be useful to know what you have prepared on the firewall side before trying to create a connection via SecuExtender.

    Hi @Jscott441
    Greeting Forum , Please try to install the latest firmware MyZyxel
    If the issue still persist. 
    1)Please kindly find if there are related logs. 

    2)Share the configuration files by private messages.
    Thank you

  • Thank you all for replying. I am using the Zyxel SecuExtender from an outside location to connect into the location with the firewall. I do not know exactly what firewall model/version it is, but this issue only started to occur once we updated the firmware on the firewall in our office, a Sophos firewall. is there anything I can do from my end that would allow the traffic through it or is it truly just an update to the firmware needed on the Zyxel firewall's side?

    Hi @Jscott441
    If the issue startd after updated Sophos firewall, Could you check Sophos if there are any logs first?
    or we can have the remote session for quickly check .

    Can you downgrade the Sophos firewall firmware or test without it?

    Is the Sophos firewall connected to a modem getting the WAN IP?
