I can not connect to kafka. A colleague says that you don’t need to specify a group, but on the php client I can’t do this.
I get an error on Java:
Group coordinator ###.###.###.###:9092 (id: 2147483646 rack: null) is unavailable or invalid, will attempt rediscovery
On the php:
SyncGroupRequest failed: Broker: Group coordinator not available: actions Refresh
Is this a problem on the receiver or sender side?
