not working for docker container logs

[SathishSuresh-opex]

I am trying to use filebeat to monitor docker container logs. But, am getting the following error with TLS way

This is how my filebeat.yml looks like -
filebeat.inputs:
- type: container
enabled: true
paths:
- '/var/lib/docker/containers//.log'

output.logstash:
enabled: true
hosts: ["logstash:5045"]
ssl.certificate_authorities: ["${CONFIG_DIR}/ca.crt"]
ssl.certificate: "${CONFIG_DIR}/filebeat.crt"
ssl.key: "${CONFIG_DIR}/filebeat.key"

In docker-compose.yml, for file beat service -

filebeat:
container_name: filebeat
hostname: filebeat
build:
context: filebeat/
args:
ELK_VERSION: $ELK_VERSION
restart: unless-stopped
command: >
sh -c "filebeat -e -strict.perms=false"
volumes:
- ./filebeat/config/filebeat.yml:${FILEBEAT_DIR}/filebeat.yml:ro

pipeline/output.go:154 Failed to connect to backoff(async(tcp://logstash:5045)): dial tcp 172.22.0.4:5045: connect: connection refused

I am stuck with this issue for past 3days and couldn't find a solution. Hope you can help here
