Unifi WLAN an Netgear und Unifi Switches VLAN Probleme

Hello Community,
the following setup is giving me headaches:
There is a mixed network that has grown over the years, consisting of [Connection > Edge Router > Edge Switches > Netgear GS728Tpp].
Various end devices, including servers, are connected to the Edge Switches.
There are different VLANs, and they all interact.
In this network, there is a Unifi WLAN solution controlled by a UCK-G2-Plus.
So far, six Access Points (also Unifi) distributed throughout the building have been working excellently. Now, additional Access Points (still Unifi) are to be installed. For this, more PoE ports were needed.
Due to availability reasons, the customer opted for the Netgear GS728Tppv2.
I have configured the VLANs on the Netgear Switch analogously to the VLANs on the Edge Switches (1-6, with 1 being the default).
I have also entered the port memberships. PVID remains 1 for all ports.
Port 24 is intended to be the trunk.
On the Edge Switches, the ports for the Access Points are configured as follows:
Trunk Port, untagged default VLAN 1, tagged for all other VLANs (works smoothly).
etc.
However, no matter what combination I try on the Netgear, I can't establish a connection to the outside.
The network adapter on my computer just receives an APIPA addresses.
However, the Access Points can communicate with the controller and are displayed there (same subnet).
If I connect the Access Points to one of the Edge-Switches, they do work perfectly.
So, the problem is most likely buried somewhere in the configuration of the Netgear switch.
The configuration of the Edge Switches is as shown below:
Switch Number 3: Port 3 and 8 are Access Points.
Switch Number 4: Port 17 is the trunk Port to the Netgear Switch
If anyone has an idea, I would be very grateful.
Addendum: The Access Points broadcast three SSIDs, each in a different VLAN.
Best regards

All the ports configured to connect as an uplink to the customer existing network as well as where the APs are connected, must be configured as tagged for each VLAN, except of the UniFi admin network
Ensure no other VLANs are active on these ports except of the UniFi (and the NEtgear switch admin VLAN) admin network in untagged.
Just the presence of the SSIDs does not proof these SSIDs and brig the correct VLAN connectivity, any attempt to connect to these SSIDs will certainly nd with Zeroconf address on most clients, lack of a correct DHCP assignment on the client, wit wont help much usually.

Thank you for your answer. But I tried that already, as this was the working configuration on the other switches.
I will spare you the screenshots of more Ts and Us.
But out of sheer desperation I went back to the basement and tried (not that i didn`t do that already last week):
On all VLANs but the default one, which i left untagged.
Trunk port tagged, uplink ports tagged
Trunk port tagged, uplink ports untagged
Trunk port untagged, uplink ports tagged
Trunk port untagged, uplink port utagged.
Nothing worked.
There has to be something else, that i am missing.
All right,
the solutin was as easy as it was stupid (on my side).
It was a faulty cable.
Will check that first in the future.
