Gree Climate stopped working after changing switch/router to mikrotik

The problem

I'm not sure what is blocking the Gree Climate but it was working well on my previous network. Now I've changed router to mikrotik and something is blocking HA to communicate to my Gree AC devices. Gree+ app is still working fine. Where can be a problem? What is needed in the network firewall to get it work?

What version of Home Assistant Core has the issue?

2024.5.2
