RDP to Tachyon not working

My Tachyon is running the desktop version with no problems connecting to an HDMI monitor (via a UGREEN USB-C hub with USB keyboard and mouse). The WiFi connection works and everything runs well. However, when I try to RDP from a Windows 11 PC, specifying the Tachyon’s IP, it will not connect.

Another user mentioned that this should work “out-of-the-box”. What am I missing?

I don’t remember if I had to enable RDP access on the Tachyon side via the settings menu. RDP works well from my Win11 machine to the Tachyon.
