java pulsar-client get broker returns localhost

[huangjun0124]

Hi, i have a pulsar server, now i connect to it as consumer in java pulsar-client-2.11.1
the service-url is configured as : pulsar://192.168.1.122:6650 which is where the pulsar standalone server running
and when the consumer is created, error occured that it can not connect to 'localhost'
Through debug, i found BinaryProtoLookupService::findBroker function, the lookup request has response :
BinaryProtoLookupService.LookupDataResult(brokerUrl=pulsar://localhost:6650, partitions=-1,authoritative=true,proxyThroughServiceUrl=false,redirect=false)
This would cause the outter function use localhost as the remote pulsar broker server, result in errors
Do anyone know how to solve this error, thanks

If I understand your issue correctly, this should have to do with the "advertised listeners" for a pulsar broker:
https://pulsar.apache.org/docs/3.1.x/concepts-multiple-advertised-listeners/

This defines the url that a broker provides during a lookup request.

Hi, this may not be the situation. The pulsar server is running by standalone, i changed nothing in the config.
Actually, this server used to run ok, but not able to be connected except for local machine after a shutdown and restart.
And the config files still remain the same, nothing modified after the install pkg is decompressed.
I wonder if anything goes wrong after a restart process of standalone pulsar server?

Tried again, using the below command:

bin/pulsar-client produce \
    persistent://public/default/test \
    -n 1 \
    -m "Hello Pulsar"

would still pop error,:
