However, curling the webhook succeeds:

curl -X POST -H 'Content-type: application/json' --data '{"text":"Hello, World!"}' https://hooks.slack.com/services/REDACTED/REDACTED/REDACTED

Technical details:

  • Redash Version: 7.0.0+b18042
  • Browser/OS: Centos 7
  • How did you install Redash: shell script for Centos 7 from justinclift

Solved.

Configured docker like so: https://docs.docker.com/network/proxy/#configure-the-docker-client with http_proxy and https_proxy

docker-compose down then docker-compose up

Slack started working! Docker added new env variables into /opt/redash/env
