Rails jobs stuck for sidekiq error broken pipeline using mqtt

I've an error when Sidekiq trying to process a Rails Job.I'm now migrating the web app to google cloud service where i set up a redis server and the broker mqtt.

The Active Job is the following:

 def publish_updatetopic = "tournament_team_category/#{@round_match.round.tournament_team_category.id}"payload = {  round_match: {    id: @round_match.id,    started_at: @round_match.started_at,    ended_at: @round_match.ended_at,    first_round_match_team: {      id: @round_match.first_round_match_team.id,      goals: @round_match.first_round_match_team.goals    },    second_round_match_team: {      id: @round_match.second_round_match_team.id,      goals: @round_match.second_round_match_team.goals    }  }}# TODO: Improve exception managebegin  MQTT_CLIENT.connect  MQTT_CLIENT.publish(topic, payload.to_json, false, 1)  MQTT_CLIENT.disconnectrescue MQTT::NotConnectedException => _e  return nilrescue MQTT::ProtocolException => _e  return nilendend

When Sidekiq try to execute this job the server show me this error:

2020-10-01 13:22:39 worker[20201001t140958]  2020-10-01T13:22:39.897Z 1 TID-gtixo1hip WARN: Errno::EPIPE: Broken pipe2020-10-01 13:22:39 worker[20201001t140958]  2020-10-01T13:22:39.897Z 1 TID-gtixo1hip WARN: /app/vendor/bundle/ruby/2.6.0/gems/mqtt-0.5.0/lib/mqtt/client.rb:556:in `write'2020-10-01 13:22:39 worker[20201001t140958]  /app/vendor/bundle/ruby/2.6.0/gems/mqtt-0.5.0/lib/mqtt/client.rb:556:in `block in send_packet'

The mqtt client.rb line 556 code is:

# Send a packet to server   def send_packet(data)# Raise exception if we aren't connected   raise MQTT::NotConnectedException if not connected?# Only allow one thread to write to socket at a time   @write_semaphore.synchronize do   @socket.write(data.to_s) endend

I can't find any solution to fix this and my jobs still in stuck.Anyone ever had this kind of problem?

Thanks
