Hello dear zyxel support team!

DNS entries added via firewall settings are suddenly no longer delivered. Nothing was changed in Nebula. After I added a new entry in Nebula under Firewall settings, it worked normally again. As firewall I have a USG Flex 200. 

Thanks!

    Hello @baba,
    Since it works normally now, and we didn't see any abnormal server logs recently. Please help us to collect information when it happens again.
    We need two diagnostic info files and the timestamp when the problem appears and disappears.
    1. collect the diagnostic info when the problem occurs
    2. collect the diagnostic info after re-push the DNS entries configure. (add a new entry or re-enable) 

    How to collect diagnostic info?
    Login to local web gui, the username/password is support/side-wide general setting password.

    Thanks,
    James

    Hi @Zyxel_James

    the error is back again. It can't be fixed anymore by adding a new entry. All entries are shown in Nebula, but not delivered via dns server. I've activated Zyxel Support Access in nebula and downloaded a diagnostic info from the usg flex 200.

    Thanks!

    Hello @baba,
    Currently, the Nebula CC webpage is suffering an unexpected outage incident, this issue is related to the incident too. We already posted an announcement on our official forum, any progress will be updated there too, please refer to
    I will keep you updated when it's fixed as well.

    Best regards,
    James

    Hi @Zyxel_James

    the issuse is marked as resolved but my error is still there. I saw you had added an entry zyxel.test.com which didnt fix the problem.

    Thanks!

    Hello @baba,
    It's an issue with DNS address record settings, we're working on it.
    If you need the DNS entries settings urgently, I can help you to add them first, please provide the DNS entry settings to me through PM.
