Mikrotik and Xiaomi Gateway

I’m trying to setup Xiaomi Gateway (Aquara) working with network behind Mikrotik.
When I use a config:

gateways:
  - mac: 34CE008D4XXX
    key: qx8rfaXXXXXXXX
    host: 192.168.1.51
  - mac: 7811DCB06XXX
    key: op70q7XXXXXXXXX
    host: 192.168.1.50
  - mac: 7811DC6C9XXX
    key: ddfu2sp7jXXXXX
    host: 192.168.1.52

then Gateways are runing fine (detected, switches working, sensors sending temperature) but only for 30 -90 seconds.
After that all stops. I can tunr on/off lights (even on gateway) by clicking switches on hassio interface but psysical switchest stop working. Sensors do not updates and goes to unavailable state.

If I remove “host: ip” from my config then flatform auara could not be set up.
I think Mikrotik somehow block MULICAST but I don’t know how to enable it.

On old simple tplink router everything works fine.

Please help me.
