Connection issue between LtAP mini LTE kit and hAP lite

Hello Everybody.

I have an LtAP configured with a SIM card to work in LTE, now I have purchased an hAp lite to use in another floor of my house but it doesn’t work.
I tried to restore the default configuration, but it still doesn’t work, so I tried to go through a non-default configuration step by step but nothing.
The strangest thing is that if I use hAP in the default configuration with another router it works.
Can someone help me? Thanks in advance.

Hi did you get this working?

Hap Lite reset with no default configuration, setup as CPE in Quickset?

Make sure you use different IP subnet on both devices if you make them both router.
Default is 192.168.88.x on all Mikrotik devices, if you want to connect two of them one device needs
a different subnet…

Need more info.
Draw a network diagram so we can see how the devices are related and setup.
