Liongard recently began a phased release of Agent version 5.4.0 on June 9. The release was terminated on June 16 after issues were identified. The 5.4.0 agent release was made available to partners on the following instances: US1, US2, US3, US7, AUS1, CA1, EU1, IND1, and UK1. Partners on all other instances should be unaffected. For some partners who upgraded to Agent version 5.4.0, the agent upgrade completed successfully, but affected agents were unable to send heartbeats to the Liongard platform and returned 503 errors. As a result, some inspections associated with affected agents may not have run as expected. During our investigation, we also identified a separate certificate-related issue with the 5.4.0 agent release. Due to these issues, Liongard has removed Agent 5.4.0 from the static download URL and agent updater path. Agent version 5.3.1 has been relisted as the current available version. Our development team has implemented a fix to address the heartbeat 503 issue, and that fix is expected to become visible within the next couple of hours. In parallel, the team is working on Agent version 5.4.1 to address the certificate-related issue. Version 5.4.1 will be made available once it has been fully tested and validated. We will provide additional updates as more information becomes available.
