Question about HTTP Request from Level 1 Course

Good morning. I’m trying to learn with the level 1 course of n8n, and I faced a problem related to the HTTP Request from getting the dataset url sended via email. I added all the credentials correctly, but I got this response from the request:

NodeApiError: The connection was aborted, perhaps the server is offline at Object.execute (/usr/local/lib/node_modules/n8n/node_modules/n8n-nodes-base/dist/nodes/HttpRequest/V3/HttpRequestV3.node.js:525:33) at Workflow.runNode (/usr/local/lib/node_modules/n8n/node_modules/n8n-workflow/dist/Workflow.js:722:19) at /usr/local/lib/node_modules/n8n/node_modules/n8n-core/dist/WorkflowExecute.js:706:51 at /usr/local/lib/node_modules/n8n/node_modules/n8n-core/dist/WorkflowExecute.js:1137:20

I’m using a local n8n.

Which http request? The quotes API seems to be down - in the mean time, here’s a list of free APIs that you could use instead (it will require fiddling a bit with the fieldnames, of course).

I tried with this database url: https://internal.users.n8n.cloud/webhook/custom-erp
