USG FLEX 200H V1.21(ABWV.0)

So I have non H Flex200 with USG60W working with Certificate site to site but can't seem to get USG60W with Flex200H working:

USG60W is set with Phase 1 Certificate zyxel-router4.ddns.net and have imported zyxel-router7.ddns.net to trusted Certificate
Flex200H is set with Phase 1 Certificate zyxel-router7.ddns.net and have imported zyxel-router4.ddns.net to trusted Certificate


from USG60W

    Ok so their is a big change on the FLEX H when it comes to  trusted Certificate on older models you can import your Certificate with USG showing as "incomplete path" and it works

    With Flex H you can't get a way with that and must install intermediate Certification and Root

    in order to get this

    Then the VPN site to site works

    update So I now test with the following to Certificate to rule out DNS:

    USG60W is set with Phase 1 Certificate dnsip1.ddns.net and have imported dnsip11.ddns.net to trusted Certificate

    Flex200H is set with Phase 1 Certificate dnsip11.ddns.net and have imported dnsip1.ddns.net to trusted Certificate

    DNS internally dnsip1.ddns.net 192.168.254.9

    DNS internally dnsip11.ddns.net 192.168.254.10

    I did Certificates IP and that worked then did

    USG60W is set with Phase 1 IP 192.168.254.9 Certificate and have imported dnsip11.ddns.net to trusted Certificate

    with

    Flex200H is set with Phase 1 Certificate dnsip11.ddns.net and have imported IP 192.168.254.9 Certificate to trusted Certificate

    That works

    But it seems the FLEX200H is not accepting the USG60W Certificate of dnsip1.ddns.net

    USG60W is set with Phase 1 dnsip1.ddns.net Certificate and have imported dnsip11.ddns.net to trusted Certificate

    with

    Flex200H is set with Phase 1 Certificate dnsip11.ddns.net and have imported dnsip1.ddns.net Certificate to trusted Certificate
