My Slack Trigger node is not receiving events from Slack despite correct configuration. Setup: workflow is published, webhook URL is verified in Slack Event Subscriptions, message.channels bot event is subscribed, bot is added to the channel, no firewall restrictions confirmed by IT. When I unpublish and click Execute step it shows Listening for test event but nothing arrives when I post in Slack. n8n instance is on acquia-it.app.n8n.cloud.
@Taeeb_Khan slack only registers one webhook url per app, and yours is the published/production one. so when you unpublish and hit execute step, n8n starts listening on a separate test url that slack doesnt know about, slack keeps sending to the production url, and the test listener never sees anything. to test, keep the workflow published and just watch the executions instead of using execute step. if its still silent while published, the url registered in slack is probably a stale test url, recopy the production webhook url into event subscriptions and re-verify.
