Cookbook upload failing with 404

Hi, i try to upload a cookbook to our chef server, but with no success.
I've installed the chef server, reconfigured it, created the organization and user. As next I installed chefdk on my workstation and created a cookbook. I created the knife.rb, downloaded the pem files, but while upload of cookbooks I get following message:

We are running our Chef Server on Ubuntu 16.04. My Chef-workstation is running on Ubuntu 18.04

Anyone idea what is going wrong?

Can you post what command you are actually running to attempt an upload?

The command I am running is:
knife upload cookbook test-cookbook.

But few second ago just solved the problem. My problem was my knife.rb in ~/.chef and not specified config file.
I had to add organisation in the url like https://chef-server/organisation/my-org and call the knife command mit "-c /path/to/config".

Thanks for quick reply anyway. Can you tell me, where can I store informations about knife, like default knife.rb?

I actually use the config.rb to store my configurations, since it is a replacement for knife.rb and all the settings in knife.rb work the same.
https://docs.chef.io/config_rb.html

If you are using the default ~/.chef location it should automatically find it since knife runs through several default paths.
pulled from "https://docs.chef.io/knife_setup.html"
The config.rb file is loaded every time the knife command is invoked using the following load order:

  • From a specified location given the --config flag
  • From a config.rb file within a .chef directory in the current working directory ex: ./.chef/config.rb
  • From a config.rb file within a .chef directory located one directory above the current working directory: ex: ../.chef/config.rb
  • From ~/.chef/config.rb (macOS and Linux platforms) or c:\Users\<username>\.chef (Microsoft Windows platform)
