Hi I got the following problem. I successfully created a Tailscale network and a user from outside the network can login and connect to my network. That part works properly. We use a Fedora Linux PC as a host (Sunshine) and Moonlight Client on a Windows 10 PC. After tinkering for hours we can now see each other but I get the following issue "Request Timed Out (Error 4)" This issue always happens after inputting the PIN which is displayed on the Windows (Moonlight) on my Fedora PC (Sunshine) the client cannot connect after that but still sees my PC online and as a viable option to connect.
Additional Info: I've asked in the Moonlight Discord but I still got no answer.
Maybe firewalld is getting in the way. You can temporarily disable it:
sudo systemctl stop firewalld
If that doesn’t work, you can see if SELinux is the issue. Temporarily disable:
sudo setenforce 0
Be sure to re-enable SELinux:
sudo setenforce 1
The firewall was the issue. How do I enable the firewall?
