Fixing OBS/NDI when it's stuck looking for sources after a restart:

1️⃣ Check Network Connection

• Make sure both PCs are on the same network (wired preferred).

  • Both PCs should be on Ethernet. If one is on Wi-Fi, this could cause issues.

  • Open Command Prompt (Win + R → type cmd → Enter)

  • Try pinging the other PC:

    ping <OTHER_PC_IP>

    Example:

    ping 192.168.1.100

    • If this fails, your PCs aren’t communicating over the network.

3️⃣ Check Firewall (Most Common Issue)

• Disable Windows Firewall (temporarily for testing)

  • On both PCs:

    1. Press Win + R, type firewall.cpl, press Enter.

    2. Click Turn Windows Defender Firewall on or off.

    3. Select Turn off Windows Defender Firewall for both Public & Private networks.

    4. Try refreshing NDI sources in OBS.

• If turning off the firewall fixes it, then re-enable it and manually allow OBS/NDI on the Gaming PC:

  • Go back to firewall.cpl.

  • Click Allow an app or feature through Windows Defender Firewall.

  • Find and check:

    • obs64.exe

    • NDI Runtime

    • NewTek NDI

    • OBS-NDI

    • If missing, click Allow another app… → Browse → Select OBS/NDI executables.

    Disable Windows Firewall (temporarily for testing)

• If turning off the firewall fixes it, then re-enable it and manually allow Moonlight.exe on the Script PC:

  • Go back to firewall.cpl.

  • Click Allow an app or feature through Windows Defender Firewall.

  • Find and check:

    • Moonlight.exe

    • If missing, click Allow another app… → Browse → Select OBS/NDI executables.

      Disable Windows Firewall (temporarily for testing)

4️⃣ Check OBS NDI Plugin is Enabled

• Open OBS → Tools → NDI Output Settings.

• Ensure "Main Output" is enabled.

8️⃣ Restart Everything in This Order

1. Turn off both PCs completely.

2. Power cycle the router/modem and switch (unplug for 10 seconds, then plug back in).

3. Start the sending PC first.

4. Start the receiving PC.

5. Open OBS on Gaming PC.

After trying these steps, your NDI source should show up. If it’s still not working, let us know!
