Jenkins ssh-agent Permission denied, please try again

Добрый день! Имею такой код:

sshagent(['user-ssh']) {
        sh "ssh -Tv -o StrictHostKeyChecking=no ${env.DEV_USER}@${env.DEV_HOST} 'ls -al /home/user'"
        sh "scp -o StrictHostKeyChecking=no ./distr/configurator.tar ${env.DEV_USER}@${env.DEV_HOST}:/home/${env.DEV_USER}"

Хочу подрубиться на хост, в credentials у меня приватный ключ юзера на этом дев хосте.
Но почему-то возникает ошибка:

+ scp -i **** -o StrictHostKeyChecking=no ./distr/configurator.tar
