Production and test webhook URLs return 404 even when workflows are active and listening. Tested with both Slack Trigger and generic Webhook nodes. Instance: leadheroai.app.n8n.cloud
please advise?

Hi @slinkyfran
It works on my end without any issues:
just make sure to publish your n8n production Slack trigger webhook, wait a bit, then paste the URL, It should work…
Thanks, but i just tried it again - as soon as i put the webook in in the request url i get the same error . the wokflow is active and i’m using the productino webhook…
actually I’ve been there😂
just try waiting a few minutes and testing again,
or create a fresh workflow to get a new webhook URL, publish it, go make a cup of coffee…

…then come back, and it should work (coffee magic works)![]()
I’ve tried it multiple times, new slack node, earlier in the day…nothing works. i think i have a workaround by using a webhook and webook response node, but still - it means the slack trigger isn’ working properly…that’s a N8N bug isn’t it?
It’s possible the connection is failing because the events aren’t ‘subscribed’ to on the Slack side, even if the URL is correct. Could you check your Event Subscriptions (Features > Event Subscriptions) in your Slack App Dashboard Slack API: Applications | Slack
From my latest tries, it does seem buggy ![]()
However, if I wait a bit after publishing the workflow, it works.. not sure what’s wrong tbh..
