Problem executing the triggers of WhatsApp Cloud API node

Describe the problem/error/question

Hi there,

I’m having a problem with the triggers on the WhatsApp Cloud API node on a self hosted n8n version i have on an VPS.

Basically, when i try to execute the trigger node, and put it to listen to events, its returns the error message bellow.

I really dont know exactly what is the cause of the problem. I tried to execute the node on another VPS that i own and it works just fine.

The only biggest difference between the two n8n configuration on the two VPS’s its that on the working one, i deployed n8n on unique service, using this template:

github.com/mateusrovedaa/n8n-postgres-redis-workers

compose.yaml

main

volumes:
  db_storage:
  n8n_storage:
  redis_storage:

x-shared: &shared
  restart: always
  environment:
    - DB_TYPE=postgresdb
    - DB_POSTGRESDB_HOST=postgres
    - DB_POSTGRESDB_PORT=5432
    - DB_POSTGRESDB_DATABASE=${POSTGRES_DB}
    - DB_POSTGRESDB_USER=${POSTGRES_NON_ROOT_USER}
    - DB_POSTGRESDB_PASSWORD=${POSTGRES_NON_ROOT_PASSWORD}
    - N8N_BASIC_AUTH_ACTIVE=true
    - N8N_ENCRYPTION_KEY=${N8N_ENCRYPTION_KEY}
    - N8N_HOST=${N8N_HOST}
    - N8N_PROTOCOL=${N8N_PROTOCOL}
    - N8N_RUNNERS_ENABLED=${N8N_RUNNERS_ENABLED}
    - NODE_ENV=${NODE_ENV}

And then used nginx as reverse proxy and certibot.

And the problematic one, i divided the service on three aps:

n8n_editor
n8n_webhook
n8n_worker

For this problematic one, i used this template:

github.com/tuliorneiva/n8n-template

And i configured domains for the n8n_editor and the n8n webhook on easypanel.

One thing i forgot to mention its that the webhook itself it’s working perfectly.

Anyone has a clue for what it’s happening?

What is the error message (if any)?
