The VLANs between the 2 routers are not working properly

Hi,

I have one problem when setting up VLAN.When I set the VLAN it doesn’t want to work properly.I have been using this method for months and suddenly it stops working.

So we have one HAP-LITE ac RB952Ui-5ac2nD which is the main one in the house.
And I have another HAP-LITE RB941-2nD-TC which is secondary.

I take a LAN cable and connect the secondary RB to ether5 of the main RB.
I create a Bridge and add VLAN30 to it for example.
I also connect ether5 to the Bridge so that it all works.
VLAN30 gets the IP address 192.168.30.1/24 for example

I go to the secondary RB and add a Bridge to it and add VLAN30 to the Bridge
I connect the bridge to ether1 and add the address VLAN30 192.168.30.2/24
And I add gateway in routes 192.168.30.1

This method worked and stopped, none of the VLAN methods work anymore

Instead of make video and try to monetize it on youtube, put a diagram and the /export of the configs on forum, and probably someone help.
(censore serial numbers, public ip, username, password and email on export but do not delete anything)

I really dont care how you configure anything, because that doesnt lead to a solution.
For instance is the second router serving as a AP/Switch or a full router.
In other words provide
a. network diagram
b. set of requirements
single or groups of users
singe or groups of devices,
what should each be able to do
what should each not be able to do.
USE case description of the work that needs to be done.
leave the configuration out of the discussion.
