Error publishing package with yarn

[Guest]

Hello,

when publishing a package with yarn into an npm feed the following error is displayed. Maybe you have some advise how to fix this. It seems that the initial login works but the publishing itself after that login does not work. See the following yarn publish output.

yarn publish --verbose --registry https://progetserver/npm/npmfeed

It's a "401" error, which means "not authorized"

In this case, you could have the wrong credentials in Yarn (or no credentials). Note that "Windows Integrated Auth" is not supported by npm or yarn.
