App service to pull image from Nexus

Question

I want to setup App Service deployment that will be pulling images from private registry - Nexus3.

I have VNET setup and pulling images over vnet is enabled. URL, username and password are properly provided.

In deployment center logs I'm getting error:

Unauthorized. Image registry server should return proper challenge with header WWW-Authenticate.

nslookup for registry works, and registry should be returning:

WWW-Authenticate: BASIC realm="Sonatype Nexus Repository Manager"

Hello ,

you need to check :

1- you have the right username and password in the deployment settings.
2-confirm auth header is correctly sent using basic auth : Authorization: Basic <base64_encoded(username:password)>

3- check from vnet that you can access the Nexus , nslookup from the console .
4-Check if Nexsus3 is configured to allow auth from external system or not .
