Hello ZYXEL Community,
during my "deep dive" with the new Firmware, i can reproduce the following error message in the easy mode.

It's comeing up, if you push the market refresh button. The LOG in the expert mode display the following error mesage:

The ISP connection is running and extranet is usable.
FW 4.31 release is in production on the USG.

    Hi @ChristianG,
    Thanks for the issue feedback. :)
    I am trying to reproduce this issue on lab device. Here is my test procedure,
    1)    Start testing with USG-60W V4.31 system default configuration file(Wan is connected, get IP from DHCP server, Internet access is available at that time).
    2)    Log in Web GUI management, it’s easy mode by default. Click the “Refresh” button on title bar.
    Switch the Web GUI from easy mode to expert mode and check the log(Monitor > Log), I cannot find the log “Connection error has occurred”.
    Is this test procedure same as you?

    I also try another case, unplug wan cable, then click the “Refresh” button. i can see the log “Connection error has occurred”.
    Can you help to check again is the Internet access available at that time?

    WAN IP is on WAN1_PPP (see screenshot).

    DNS Forwarder is configured with the ISP default DNS Server-IP's (trough DHCP)
