HTTP/1.1 407 Proxy Authentication Required

MadMax — Tue, 26 May 2020 18:39:05 GMT

I'm using the downloading tool with a correct URL and I got the following error:

HTTP/1.1 407 Proxy Authentication Required
Proxy-Authenticate: NEGOTIATE
Proxy-Authenticate: NTLM
Proxy-Authenticate: BASIC realm="MillwardBrownDC"
Cache-Control: no-cache
Pragma: no-cache
Content-Type: text/html; charset=utf-8
Proxy-Connection: close
Set-Cookie: BCSI-CS-f89c73c53b0f638a=2; Path=/
Connection: close
Content-Length: 849

I've read that it should be due to my company is using a proxy for some outbound connections but the thing is that when I try to do this with an internet browser, I don't have any problem.

If I do this coding with Java, I don't have problems either and I don't need to tell java any user or password to connect through any proxy.

The URL that I'm trying to access belongs to an OSM API. I've tried using a URL to access to the Google Places API from Alteryx and it works like a charm.

Any idea how to solve this?

Thanks!

It seems that has nothing to do with any proxy authentication since I tested it from home too and I got the following error:

HTTP/1.1 400 Bad Request

Server: Apache/2.4.18 (Ubuntu)
Vary: Accept-Encoding
Content-Encoding: gzip
Content-Length: 441
Connection: close
Content-Type: text/html; charset=utf-8

Sadly, I still have no idea how to solve it.

Hey, @MadMax I've been through dozens of variations on this issue.

Can you tell me what you see when you get to the LAN Settings screen?

Internet Explorer --> Go to Tools --> Internet Options --> Connections Tab --> LAN Settings

Hi @patrick_mcauliffe,

Thanks for you reply.

Here it is what I see in my LAN Settings screen:

Thanks in advance!

@MadMax

That's about what I expected.

There are a few options, almost all involve talking to your IT Security team, but let's just try a workaround first.

Delete the text in the address box, then uncheck the first two boxes.

Try to run your workflow again immediately after clicking OK.

Hi Patrick,

That's solved a problem that I was just having with another API (thank you very much!) but not the one that I still have with the OSM API.

I'm trying to download a JSON object from this URL. I can see on my browser (Chrome/Firefox/IE) and, as I've already said, in my Java code, but with alteryx I got the following error.

I'll try later from home to see if now it's working.

Thanks!

@MadMax

In the Download tool configuration, uncheck "Encode URL".

We use VDI and cant edit LAN settings, thus need a way to send proxy somehow via Download tool itself.
Can't we send proxy as 'Parameter' inside Parameter Tab as Query etc.
Please advice as we are stuck due to Proxy settings, unable to establish REST API calls.
