Firewall?

[Peterl627]

firewall is open

[RayneYoruka]

Are they on the same network?, are they both on ethernet? does NDI tools pick the signal on the recieving end?

[Peterl627]

same network wifi, no it doesn't show up on ndi tools either

[RayneYoruka]

Then this might be network isolation. Which it's a security measure a lot of routers toggle by default. Please investigate.

I don't know why it just happened it was working fine 2 weeks ago; last week end it didn't work anymore.

You will need to vetify with NDI studio monitor.

Otherwise it might just be firewall. This are the ports used by NDI:
