Asus GT-AX11000 - Firewall is blocking MQTT Port 1883

Hi

after the update from Version 3.0.0.4.384.9566 to a newer firmware (3.0.0.4.386.41700,
3.0.0.4.386.43129 or 3.0.0.4.386.44266 ) i have some weird behaviour with my AX11000
because the firewall blocks the MQTT port :1883.
Its WAN port is connected to a Fritz Box for the internet connection.
Both router have there own IP range and are able to communitacte together.
I also can ping from network to network and also open webinterfaces on both.

The AX11000 network have a MQTT server with standard port :1883.
The Fritz Box network have a few devices that connect to this mqtt this server.
BUT the AX11000 's firewall blocks for some reason this 1883 port.
When i disable the firewall my devices connect to the mqtt server without any problems.
If i activate the firewall again the connection remains ?!
If I then disconnect the devices from the power and plug them in again, it is blocked again 😄

With the 3.0.0.4.384.9566 firmeware all works fine 😞

Can you please take a look at this?

THX 😃
