I suspect that something blocked on our side, but if open connector url, the page successfully loaded while reirected to https://archive.ubuntu.com/ubuntu.
Any ideas how to debug the issue?

Help needed to configure Debian feed connectors!
We need to setup repository for Ubuntu systems. I created new Debian feed with 2 connectors:

Type: Debian2
Name: Archive Ubuntu
Url: http://archive.ubuntu.com/ubuntu
Timeout: 1 min
Athentication: anonymous

Type: Debian2
Name: FTP Debian
Url: http://ftp.debian.org/debian
Timeout: 1 min
Authentication: anonymous

Both of them with status: Error.
When tried to search for some package I am getting:
An unexpected error occured while listing packages: The remote server returned an error: (404) Not Found...

Any ideas? What I am missing?
Thank you in advance!

@stevedennis
Make sense. I removed connector and now I see uploaded package.
Do it check for vulnerabilities?

Here is it:

Hello,
I created new Visual Studio Extensions feed. While trying browsing the feed I am getting fololwing error:
An unexpected error occurred while listing packages: An error occurred while parsing EntityName. Line 27, position 247.. Additional information has been logged in the diagnostic center.
I tried to delete and create a new one - same error. And I am able to upload packages, but I am not see them.
Any ideas what problem is?
Thank you in advance,
Arkady

I am testing ProGet for offline system.
So, I have Internet facing ProGet with npm connector to npmjs.org and offline server.
I tried npm install with some package.json file on server with access to Internet. When I check .npm folder on the server I did't find some packages. I checked on the feed and they appear as Remote packages.
I can go to specific package version and "Pull to ProGet", then it will appear on file systems as well.
Why it happens? And how can I be sure that all packages are downloaded locally?
Thank you in advance!
