OSC won't start with VPN on

Ok, so I have a VPN. If the VPN is off, OSC works, and when it’s on it doesn’t and I get this in the logs:
“Could not Start OSC: The requested address is not valid in this context”

Is there any way I can get OSC to work with my VPN ON.

The VPN software might matter.

Maybe ask the VPN maker about it? They’d be in a better position to download VRChat and see what the network interfaces are doing while the VPN is running. Especially if you’re not wanting to name the service you’re using.

Edit: Maybe you can tell VRChat a specific IP address to bind to, like 127.0.0.1

Thank you. 127 wasn’t the way to go, but here’s what did for future problem havers.

Launch option for VRChat in steam

–osc=9000:[local lan IP]:9001

Then the programs that needed to yell at VRChat needed to be excluded from the VPN, which is fine because I can split tunnel.

That’s it.

Thanks again.


Was having error getting OSC software (VRCT for translation) to send messages to VRChat’s chatbox.
“The requested address is not valid in this context”
Checked logs in C:\Users\username\AppData\LocalLow\VRChat\VRChat and error was there too.
Notification would show up in VRChat showing the connection of VRCT osc to the localhost and port 127.0.0.1:12345 but there was nothing on the OSC debug console.

Solution was to start VRChat and OSC software without VPN on. Then turn VPN on later.

If I turn VPN on and start VRChat and VRCT after, it does not work.

Already added the programs to my VPN split tunneling and windows firewall.
