Telion Wi-Fi mode troubleshooting.

The link does not open on my phone

In Wi-Fi mode Telion runs a small server inside your DAW. Your phone connects to your computer directly over the local network, nothing leaves your home. That is why anything that filters connections on the computer or on the network can stop it. Go through the list from top to bottom, each step takes a minute.

1. Same network

The phone and the computer must be on the same Wi-Fi network. A guest network, a second SSID of the same router, or the phone on cellular will not work. Turn off any VPN on the phone: with a VPN active, the address 192.168.x.x goes into the tunnel and never reaches your computer.

2. Telion says "WI-FI BLOCKED BY MACOS"

When you press START STREAM in Wi-Fi mode, Telion checks its own server over the network. If the check fails, this window opens and the display shows LOCAL NETWORK BLOCKED. That means the computer accepted the connection and something on the computer killed it. The phone shows "Safari can't open the page because the network connection was lost". The steps below fix it.

3. macOS: Local Network permission

Since macOS 15 every app needs permission to talk to devices on the local network. Your DAW must have it.

System Settings, Privacy & Security, Local Network. Turn the switch on for your DAW (Logic Pro, Ableton Live, Cubase and so on). If the DAW is not in the list, quit it completely with Cmd+Q, open it again and press START STREAM: macOS will ask, choose Allow.

If the switch was already on, turn it off and on, then quit the DAW with Cmd+Q and open it again. Permission granted while the DAW is running does not take effect until restart.

4. macOS firewall

System Settings, Network, Firewall. If the firewall is on, click Options and find your DAW in the list. It must say "Allow incoming connections". If it says "Block incoming connections", switch it. This block usually appears after someone clicked Deny when macOS first asked about incoming connections.

5. Third-party firewalls and VPN apps

Apps that filter network traffic per application block Wi-Fi mode silently. The most common ones:

Little Snitch, LuLu, Radio Silence and similar: allow incoming connections for your DAW on ports 7420 to 7429, or switch the filter to allow mode while you stream.
Tailscale, ZeroTier, corporate VPN clients: if an exit node is active, enable "Allow LAN access" or turn the exit node off. Quitting the app is often not enough, its network extension stays active until you disconnect or reboot.
Antivirus and endpoint security agents: add your DAW to the allowed list or ask your administrator.

To see what is installed, open Terminal and run:

systemextensionsctl list

Everything marked "network-extension" in that list can filter traffic.

6. Router

Some routers isolate clients from each other, the setting is called AP isolation, client isolation or guest mode. Turn it off for your home network. A quick test: if another device on the same network, for example a printer or a NAS, opens in the phone browser, the router is fine.

7. Port

Telion uses port 7420. If it is taken, the next free port up to 7429 is used and the link in the plugin shows the real port. Always use the link or the QR code from the plugin, do not type the address from memory.

Still not working

Send us the log, it records every connection attempt: ~/Library/Telion/telion.log on macOS, %APPDATA%\Telion\telion.log on Windows. Attach the last 30 lines to your message to [email protected] together with the name of your DAW and macOS or Windows version.
