My client configured on the OBS 6,000kbps softaware. But the server does not accept more than 4,096? Where I increase in wowza so that I can transmit at 6,000Kbps
Can I ask what use case do you need 6Mbps?
Unfortunately, we can help increase the HEAP and memory on the Wowza side, but not what you can adjust for your bandwidth needs for that much data. You would need to talk to your provider, where the server is hosted, or check that the encoder can reach the server with the appropriate bandwidth, again your provider.
