API Help - Error: Download (2): Error transferring data *URL*: Failure when receiving data

[scott-tolan]

Hope someone can advise/help please.

I have recently installed Alteryx Designer x64 2022.01 and Alteryx is working fine for the majority of the workflows that I have created - at this stage this it is mostly joins and formulas - just dipping my toe into this world!

Our team (only two of us) are moving our current operational reports from a SQL and Microsoft Reporting Service to Alteryx and Tableau solution which will utilise a vendors API to replace the SQL query aspect.

Just to set the scene we are using the same type of laptop, the same OS provided by our organisation, connecting to the same VPN and have checked lot of the network settings which all match.

The trouble I am have is using the download tool to obtain a bearer token, when the call is made I get this error -

The error message I get is "Error: Download (2): Error transferring data *URL*: Failure when receiving data from the peer."

Here's my workflow which runs fine on my colleagues machine.

The token URL is pointing to the vender authentication endpoint which will obtain a token for the rest of the API calls, here's screen shots from the download config as I don't upload the workflow as it has authentication keys embedded.

Basic

Payload, values removed

Generally confused why it would work for my colleague but not me!

Somethings that I have done/checked so far:

• Re-created the authentication stage in a new workflow but still see the same error
• Tested the API call in PowerShell with the same credential and parameters, runs successfully so shows I can connect to URL
• Created another API flow using a totally different URL (also runs successfully)

Having looked at the community posts it seems a few have had this issue before and it may be related to firewall/proxies. But myself and my colleague are using the same VPN connection which was configured by the same IT department. We have also compared many of the different user settings both in Alteryx and Windows and seem to be the same.

Any thoughts would be much appreciated!

I would check back with your IT department for any role or user-specific firewall permissions.

Just to close this, unchecking the option 'Use AMP Engine’ in the workflow configuration fixed the issue.

@scott-tolan  what version of Alterxy Designer are you using?

Hi Patrick,

I am using Version: 2022.1.1.42590 Patch: 3

I have rolled back to a previous version, and still had the same issue. 

To be honest, I'm still not sure why my colleague can have this option checked and run their workflows fine, but it doesn't work for me. Just glad to have it working at the minute!
