401 Unauthorized The 401 (Unauthorized) status code indicates that the request has not been applied because it lacks valid authentication credentials for the target resource. The server generating a 401 response MUST send a WWW-Authenticate header field (Section 4.1) containing at least one challenge applicable to the target resource.
Failed to load url1: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'mywebapp' is therefore not allowed access. The response had HTTP status code 401.
8 When building a REST API that doesn't use HTTP basic authentication (but something else like an api-key) and the client provides invalid credentials, what HTTP Status Code are you supposed to return? 401 Unauthorized or 403 Forbidden?
While pushing the docker image (after successful login) from my host I am getting "unauthorized: authentication required". Details below. -bash-4.2# docker login --username=asamba --email=anand.
In my case , that was only unauthorized and what saved my day is to login in commandline like docker login theaddressoftheimage then it promts for the credentials then you re free :)
This webpage discusses the 401 Unauthorized error due to invalid credentials and provides solutions to resolve it.
I got Unauthorized also because of a permission issue. For some reason when mvn is being executed in a Docker container, not under 'root' user, (how the project was build there), it returns 401.
