Device sharing not working in a very specific setup

Hello,

I have a rather bizarre issue and I hope someone can shed some light on this... But I need to start with a detailed description of my setup, as it is essential for the issue:

There are two rooms involved:

Study:
(1) A stationary PC computer running Windows 10, connected to the home network through Ethernet (via a Gigabit switch).
(2) A 2.4 GHz WiFi router, connected through Ethernet

Living room:
(3) An HTPC running Windows 7, connected through Ethernet, specifically, it is connected to:
(4) A 5 GHz WiFi router, connected through Ethernet

Here is my problem: when I use my laptop in the study while connected through WiFi to the router (2), I can share my input device (Razer Hydra) with the stationary PC (1) without problems. When I move it to the living room, it does not work neither through the WiFi from router (4) nor through Ethernet (the router (4) Ethernet port or through the wall port). That is, I can see the server with all the devices on (1), however, I cannot use any device I select (sometimes there is an error message, sometimes there is not).

BUT the HTPC which is also connected with the network through the very same Ethernet connection can share the device without problems. What could be the reason for that???

The server log:
