Hi @fengcheng

Bind address is addres for graylog input which will listen to. Address 0.0.0.0 mean all addresses, so it will listen on all network interfaces that graylog box have. So change bing address to 0.0.0.0 from your defined address.

Check if you didn’t create more than one inputs that listen in same port. You can only create one input which listen in specific port otherwhise it will fail to start, because port is already binded by another input with same port.
