If you check the webhook url in the node does it still show as http://localhost:5678 or does it show your domain?
If it does show as localhost setting the WEBHOOK_URL env option will help, If it is showing as your domain does Clickup show any errors for the connection?
It should be your full custom URL with https://. If it is localhost:5678 it means you didn’t set the WEBHOOK_URL env option on setup and that would be the fix
Usually doesn’t work without it. I had an issue with clickup triggers where i had a typo in https and triggers weren’t working, when i fixed the typo it started working.
Also, sometimes i have found it can take up to a minute for the events to come in from clickup
Also, for now for your testing set the event to * which will send all events. (unless you have others doing stuff that will keep triggering it)
But that will tell you if it’s your issue or clickups issue
Does a normal webhook worklfow work ok? I have just tested the clickup trigger on my n8n install and it appears to be ok. I personally don’t use Cloudron as to me it is another layer in the process that doesn’t need to be there.
Don’t mean to beat a dead horse, that is just the most common issue. People post about this all the time and it is almost always that.
Like @Jon asked, does the regular webhook trigger work ok for you? The clickup trigger is essentially just a webhook trigger under the hood, it just registers the url for you (which is why it’s important for it to be set correctly)
It could also be a firewall issue or getting mixed up in your reverse proxy, so check all of the relevant logs and see if anything is being blocked.
As a trouble shooting step you can set up a normal webhook trigger. Then manually subscribe to the clickup webhooks with an http node using the webhook url. This is what the clickup trigger does under the hood.
