5.7.4 What Can Go Wrong?

If you see [notice] or [alert] log message such as below, please check ZyWALL/USG SSL Selected
1
User/Group Objects settings. Windows 10 users must use the same Username and Password
as configured in ZyWALL/USG to establish the SSL VPN tunnel.

If you uploaded a logo to show in the SSL VPN user screens but it does not display properly, check
2
that the logo graphic is in GIF, JPG, or PNG format. The graphic should use a resolution of 103 x 29
pixels to avoid distortion when displayed. The ZyWALL/USG automatically resizes a graphic of a
different resolution to 103 x 29 pixels. The file size must be 100 kilobytes or less. Transparent
background is recommended.
If users can log into the SSL VPN but cannot see some of the resource links check the SSL
3
application object's configuration.
If the ZyWALL/USG redirects the user to the user aware screen, check whether the user account is
4
included in an SSL VPN access policy or not.
Changing the HTTP/HTTPS configuration disconnects SSL VPN network extension sessions. Users
5
need to re-connect if this happens.
