Publishing to sonatype fails with 401

[Martmists-GH]

I made sure to create a token and stored the credentials in my properties file, and I am sure they are set as username/password.

I configured the nexusPlugin as described in the readme:

nexusPublishing {
    repositories {
        sonatype {
            nexusUrl.set(uri("https://s01.oss.sonatype.org/service/local/"))
            snapshotRepositoryUrl.set(uri("https://s01.oss.sonatype.org/content/repositories/snapshots/"))

            username = if (project.hasProperty("mavenCentralUser")) {
                project.properties["mavenCentralUser"] as? String
            } else {
                System.getenv("MAVEN_CENTRAL_USER")
            } ?: error("No maven user found")
            password = if (project.hasProperty("mavenCentralToken")) {
                project.properties["mavenCentralToken"] as? String
            } else {
                System.getenv("MAVEN_CENTRAL_TOKEN")
            } ?: error("No maven token found")
        }
    }
}

but I still get
