Maven "Could not find artifact" of <THIS PACKAGE> when "mvn deploy" to repository in Gitlab

I'm trying to deploy a maven artifact to our self hosted Gitlab server. It is finding the server OK, but fails when trying to find the artifact I'm currently trying to upload.

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project topic-lib: Failed to deploy artifacts: Could not find artifact com.company:topic-lib:jar:1.0.0 in gitlab-maven (http://git.company.no/groups/some/-/packages/maven) -> [Help 1]

Any idea what causes this error?
