We were notified that jobs were “stuck” on one of our Microsoft 365 environments, so we proceeded with the upgrade to version 8.1.1. However, after the upgrade, the jobs remained stuck.
I cleared the NATS directory and restarted all services. This resolved the usual symptoms we see when the NATS cache is the issue—there are no running jobs now—but starting any job results in it getting stuck at the "Detecting" stage. No data is processed.
At this point, we have another large Veeam Backup for Microsoft 365 environment that has stopped working unexpectedly. The 8.1.1 update did not resolve the issue.
Support Case #07670283 – Severity 1.
