Peplink B One + TP-Link managed switch + Pepwave Ac one mini

Dear Community,

I need some help to get my setup working.

I recently upgraded from Soho MK3 to the B One.
A TP Link managed switch is connected to the B One ( Port 1 Trunk Any)
My AC One Mini is connected to the managed switch, I have access to the web UI.
Mesh and SSIDs were setup on both B One and AP. The B One even can see the AP. Guest VLAN 10 and IOT VLAN 20.

My issue is, that whatever I configure I cannot connect to the SSIDs on the AP. As soon as I get near the AP where the handoff should happen, connection is lost and my devices (mobile phone, laptop, tablet) are not getting any ip address.

In addition, what is really strange, when a device is connected to the wifi VLAN 10 on the B One, I can also see the device on the AP in the client list but with a very strange ip address (169.x.x.x).

TP Link managed switch is configured as following:
Port 1 is connected to the B One. Default VLAN 1 has all ports as untagged.
Port 2 is connected to the One Mini AP.
VLAN 10 was added as Port 1 untagged and Port 2 tagged (PVID port 1 and 2 = VLAN 1)
VLAN 20 was added as Port 1, 3 and 4 untagged and Port 2 tagged (PVID port 1 and 2 = VLAN 1, Port 3 and 4 = VLAN 20)

I hope you can help me in my setup.
Thank you,
S.
