While looking at T393542: integration-agent-docker-1061 is offline, the agent log has:
ERROR: Failed to authenticate as jenkins-deploy with credential=jenkins-deploy-toolforge
That is a credential that was set for T157893 to have a Jenkins agent running on Toolforge. To connect to the VM inside the integration project, we use another credential.
There are three affected hosts, all got created recently (March 20) by @thcipriani
integration-agent-docker-1060/config.xml: <credentialsId>jenkins-deploy-toolforge</credentialsId> integration-agent-docker-1061/config.xml: <credentialsId>jenkins-deploy-toolforge</credentialsId> integration-agent-docker-1062/config.xml: <credentialsId>jenkins-deploy-toolforge</credentialsId>
I'll fix them.
