How to properly set up Mikrotic hEX for use with Tricolor TV?

Question

network hardware

At home, a simple network was created on two Mikrotiks:
Mikrotic hEX, which is also a router, receives the Internet over a twisted pair cable through a dhcp provider. It also runs dhcp for all devices on the internal network and DNS. All ports are bridged, firewall is configured by default. The following are connected to it:
- Mikrotic hapAC as a WiFi access point
- Tricolor TV set-top box as an Internet TV
- PC as a home computer
Regularly connected to the WiFi access point
- 5 wifi devices
Problem:
The bottom line is that for some reason that is not yet clear, when watching TV channels through Tricolor TV on the Internet, the tricolor prefix regularly throws an error "34 - The channel is currently unavailable, try again later." and immediately after it throws error 28 "No access. To restore viewing, restart the device or try again later (error 28).", information on which is hard to find on the Internet, and the proposed solution: restart the console and you will be a miracle.
I sin on the router settings, because errors fly out with enviable regularity. Previously, there were problems with connecting the iphone: it turned out that by default the Mikrotik dhcp server reissued ip for devices every 10 (!) seconds, which the iPhone did not like, corrected and now everything is ok.
I still assume that somewhere there are standard settings related to reconnecting devices, and they interfere with the tricolor, maybe, by analogy with dhcp, Mikrotik does something with the tricolor every n seconds, but it does not take it out due to its wretchedness.
