I have not been able to use any RDP client on Android (aFreeRDP, aRDP Pro, Remote Desktop Manager) to connect to gnome-remote-desktop because connections keep being dropped after some time of usage. RDP and mDNS is allowed through the firewall.
I also occasionally experience issues with the host machine suddenly becoming unreachable over the network requiring a reconnect to the router. The hostname is set to static. This is reproducible with firewall disabled.
Edit: Still clueless. Problem appears unpredictability. I thought it was my DECO mesh network but it was not.
I currently use Fedora Linux 42 (Workstation Edition Prerelease)
Model: Lenovo Legion 5 15ACH6
Kernel: Linux 6.14.0-63.c42.x86_64
gnome-remote-desktop.x86_64 48.0-1.fc42
avahi.x86_64 0.9~rc2-2.fc42
