hi everyone, is it just me or in the course 2 the api does not work?

https://api.quotable.io/quotes

(the step is close to the end of Understanding the data structure | n8n Docs)

my error code is:

Problem in node ‘HTTP Request‘

The connection cannot be established, this usually occurs due to an incorrect host (domain) value

here is the full dump:

It looks like n8n is unable to resolve the host for the API, meaning the URL provided in the HTTP Request node is being interpreted incorrectly. This error usually happens when there’s an issue with how the host is set, for example:

The URL might include extra characters (such as markdown formatting like square brackets) that prevent proper resolution.
There may be a typo or unnecessary characters in the host/domain value.

To troubleshoot, try the following steps:

Verify the URL
Make sure the URL is entered correctly. It should be:
```
https://api.quotable.io/quotes
```
Remove any markdown or formatting characters (like [ ]) from the input.
Check for Extra Characters
Sometimes copying from documentation (or a course) may include markdown artifacts. Ensure that the URL in the HTTP Request node is just the plain URL without extra symbols.
Test the API Endpoint Externally
You could test the URL in a browser or a tool like Postman to confirm that the API endpoint is valid and reachable from your network.

By ensuring that only the correct URL is provided (without any markdown-specific characters), your HTTP Request node should be able to resolve the domain and connect to the API as expected.
