Disable any firewall that is in use from NDI sender to receiver. If that works, review any firewall exceptions that you may need.

We tried NDI Streaming in webOS and we faced the similar issue. We don't have any firewall exceptions.

our case: ndi_product metadata is received but video frame metadata is not received.

Please provide any suggestions on the above issue.
