Observed behaviour

While trying to upload using the MinIO-Plugin, we always get the error:

Problem storing objects in Minio: http://jenkins-master-host-fqdn: Name or service not known

This host name is not being used in any configuration or environment variable. Also, the configured Jenkins URL is https://our-jenkins-master.domain and not http://jenkins-master-host-fqdn

The configured hostname https://our.minio.server is not to be found in the error message.

Expected behaviour

Uploads should be attempted against the configured host, not the physical Jenkins master host name.

Workaround/Mitigation

There is not enough debug output for further investigation.

Configuration and further information

Declarative pipeline code snippet

minio bucket: 'mybucket', credentialsId: 'minio-credentials', excludes: '', host: 'https://our.minio.server', includes: 'foo/bar.baz', targetFolder: 'my/target/folder'

The issue occurs regardless of the underlying executor (i.e. Linux vs. Windows).
