After upgrading from 9.4.0 to 9.4.5 over the weekend, a job failed this morning with the error
Exception in Task: Login failed, reason: No such user
The task that fails runs a task on another server in a different domain. Both VisualCron's were 9.4.5
On the server in the other domain, I rolled back to 9.4.0 and the task worked.
