DDNS on a sub domain using ACL groups not always working

[#1]

Hello,

In a subdomain I have allowed DDNS update using an ACL group.

Within this ACL group there are multiple other ACL groups and in those groups ip addresses are configured.

Now I have setup a new group with a subnet in there that must be allowed for DDNS on the subdomain and this new group is added to the main ACL group which is set in the DDNS parameter of the subdomain.

However I see in the logs that the clients are still being denied for doing DDNS updates.
Is there a limit of amount of ACL groups added to an ACL group ?

Kind Regards,
