Hi,
Thanks for the verification, this was actually one of my assumed cases covered under the results EMAIL-*, it returns a 400 error, full error message is above.
I have implemented a manual work around that unfortunately adds to the cognitive load on our development teams. While a resolution is not urgent, it would be appreciated.

Hi,
Could you point me to your documentation detailing exactly how to connect to an Azure DevOps NPM feed using a connector and personal access tokens. This will save me from testing all of the permutations.

Re: ProGet Connector to VSTS / Azure DevOps
Hi,
According to the case (PG-1409) this was fixed in 5.1.16
I am using a server on 5.2.24, and am having issues connecting to an Azure Devops npm feed with a connector.
I can successfully make a nuget connector from the same Proget server to the same ADO organisation, and can make an NPM connection to registry.npmjs.org.

I tried 3 username variants:

1. my email which is used to login to Microsoft, like in the Nuget connector (EMAIL)
2. Random name, like in the npmrc (RNAME)
3. Empty name as described in the referenced case (ENAME)

I have tried 2 password variants:

1. Personal Access Token generated in ADO, as used in the nuget connector (PAT)
2. Encrypted PAT, as used in the npmrc (EPAT)

Both email based runs (EMAIL-*) returned a 400 error:

Both empty username (ENAME-*), and the one with a random name and PAT (RNAME-PAT) returned a 404 error:

Error processing JSON: System.Net.WebException: The remote server returned an error: (404) Not Found.

The random name with encrypted PAT (RNAME-EPAT) returned a 401:

This looked like it was working, but there was an issue with the PAT. I issued another PAT with full API access from and Organisation Admin and tried again, with the same results.

I have run out of ideas, any assistance would be appreciated.
