Failed to fetch, from repository: chocolatey-proxy java.io.IOException: Invalid nuget feed XML received

[cristianburca]

Hi,

I've setup a nuget group called chocolatey-group having chocolatey-proxy and chocolatey-hosted inside into my Nexus and got the below issue when running choco install googlechrome --version 98.0.4758.102 -s nexus

Any clue?
Best regards

If you compare these in terms of output, you will see some differences.
https://www.nuget.org/api/v2/Packages(Id='AWSSDK.Core',Version='3.7.1.4')
https://chocolatey.org/api/v2/Packages(Id='googlechrome',Version='98.0.4758.102')

I've converted this over to a discussion.

@cristianburca based on the error you are receiving:

Parsed xml has an unexpected start tag: 'html' (expected 'feed' or 'entry')

It sounds to me like you "could" be running into a rate limiting scenario, where an HTML page is being returned stating that you are being rate limited, instead of the main packages feed which is what is expected.

When this happens, are you able to access community.chocolatey.org directly in the browser?

[cristianburca]

yes, community.chocolatey.org is accessible everywhere. Comparing below urls, I can see some different outputs.
nuget --> https://www.nuget.org/api/v2/Packages(Id='AWSSDK.Core',Version='3.7.1.4')
choco --> https://chocolatey.org/api/v2/Packages(Id='googlechrome',Version='98.0.4758.102')

There are different repositories, I know, but is that normal? I notice standalone on true for the xml.
