ProGet mono 5.3.15-5.3.17 docker login always 401

[shijiyong_6709]

We run ProGet mono docker on centos 7.4, network architecture is:
user -> Kong(Nginx) -> ProGet

Web.BaseUrl is set to: https://proget.company.com

docker login -u admin or other users, always response HTTP 401.
We set docker proxy, use fiddler capture https flow, the requests sequence seems like this:

1. docker request https://proget.company.com/_v2/xxx, proget response 401, with AUTH header and realme info, response header is same to Web.BaseUrl's value
2. docker request with basic auth, proget response bear token
3. docker reqeust with 2. bear token, proget response HTTP 401, login fail.

ProGet 5.3.15, 5.3.17 have same issue, change to use .net core can solve this problem.

Hi @shijiyong_6709,

I just wanted to confirm that you are using docker login -u admin https://proget.company.com and not docker login -u admin. Is that correct?

The first thing we need to figure out is if the problem exists in your ProGet configuration or in your nginx configuration. Can you start with temporarily allowing anonymous access to your Docker registry in ProGet, does Docker pull work then?

Thanks,
Rich
