i am using https://cors-anywhere.herokuapp.com/ with port 443. I get "Not found because of proxy error: Error: connect ECONNREFUSED" when not using port 443

How to reproduce? curl https://cors-anywhere.herokuapp.com/ gives a succesful response.

https://cors-anywhere.herokuapp.com/api.bufferapp.com/1/profiles.json?access_token=[for security purposes I emailed you this]

I performed a GET request and got: "Not found because of proxy error: Error: connect ECONNREFUSED." Note that I successfully made that request via JSONP.

Reproduced error on the live server.
When I launch a local instance of Cors Anywhere (on localhost:8080, node server.js), the API call completes successfully.
When I create a new Heroku instance, the API call also works as intended.
Did you make an excessive number of API calls to buffer? Perhaps they've (temporarily) blocked my server.

Try out https://cors-anywhere-eu.herokuapp.com/. The source code is identical to cors-anywhere.herokuapp.com, but it's hosted in Europe instead of the US. To try out:

1. Visit https://robwu.nl/cors-anywhere.html.
2. Open the JavaScript console and set cors_api_url = 'http://cors-anywhere-eu.herokuapp.com/';
3. Paste the URL in the textbox at the top and click on GET.

Ok, that does indeed work. When I use the European server in Fiddler, however, I still get the error (Not found because of proxy error: Error: connect ECONNREFUSED). Do you have any idea why this happens?

It appears that the Buffer API cannot be accessed over http. Calling the Buffer API without any proxies also results in an error if you use http:

$ curl -vv 'http://api.bufferapp.com/1/profiles.json?access_token=[api key here]' -H 'X-Requested-With: Whatever'
* Hostname was NOT found in DNS cache
* Adding handle: conn: 0x7ca560
* Adding handle: send: 0
* Adding handle: recv: 0
* Curl_addHandleToPipeline: length: 1
* - Conn 0 (0x7ca560) send_pipe: 1, recv_pipe: 0
*   Trying 54.225.178.31...
* connect to 54.225.178.31 port 80 failed: Connection refused
* Failed to connect to api.bufferapp.com port 80: Connection refused
* Closing connection 0
curl: (7) Failed to connect to api.bufferapp.com port 80: Connection refused

To solve the problem, don't omit the scheme (https) and use the full URL.

https://cors-anywhere-eu.herokuapp.com/https://api.bufferapp.com/1/profiles.json?access_token=[api key here]

That works! I think they changed something recently since I used to be able to use a proxy without adding the scheme. Nevertheless, I appreciate your help.
