Unable to fetch logs in Loki from a remote Promtail agent

We have Loki Server up and running on a Linux Instance as service; I can scrape the logs from localhost using Promtail. I have installed Promtail on another Linux Instance in the same subnet; But when I try to scrape logs from other Linux Instance using Promtail its not working.

I have used below config for Loki:

config:
auth_enabled: false
ingester:
chunk_idle_period: 3m
chunk_block_size: 262144
chunk_retain_period: 1m
max_transfer_retries: 0
lifecycler:
ring:
kvstore:
store: inmemory
replication_factor: 1

  ## Different ring configs can be used. E.g. Consul
  # ring:
  #   store: consul
  #   replication_factor: 1
  #   consul:
  #     host: "consul:8500"
  #     prefix: ""
  #     httpclienttimeout: "20s"
  #     consistentreads: true

        labels:
        job: test-log
        env: dev
        host: localhost
        path: /home/ec2-user/test/*.log

Your problem could be solved?? I have the same problem
