    Error: VMware vCenter No Healthy Upstream

    In the context of software development, Upstream is the action of sending package or patch to the administrator to be integrated into the source of that particular software. And “No healthy upstream” is a software error that prevents the operation of an application.

    After installation or upgrading to vCenter Server Appliance (VCSA 7.0 Update3), when accessed to vCenter UI url (https://vcenter:443/ui), you may encounter an error: no healthy upstream. The is because of some unexpected parameters/bugs while deploying vCenter.

    You can access vCenter Server Appliance Management Interface at port 5480 and check the services, if all services show as healthy but you still cannot access web client, you need to change network settings from vCenter Server Appliance Management Interface.

    In this article, I will focus on this error and offers detailed steps to fix vCenter no healthy upstream.

    Backup Solution to Prevent Virtual Machine Crashes

    vCenter Server is a very convenient official platform for centrally managing ESXi virtual environments and large numbers of VMs on it. A single vCenter Server instance can support a maximum of 1,000 hosts, 10,000 powered-on virtual machines and 15,000 registered virtual machines.

    However, vCenter Server lacks the capability for virtual machine backup, making backup software a widely embraced solution. Opting for a professional backup tool offers greater efficiency compared to relying solely on built-in features.

    Here I introduce you to a VMware backup software — AOMEI Cyber Backup. It automates the backup process of multiple VMs managed by vCenter Server, and sends email notifications if there’s an error.

    Agentless Backup: create complete and independent image-level backup for VMware ESXi and Hyper-V VMs.
    Multiple VM Backup: batch backup large numbers of VMs managed by vCenter Server, or multiple VMs on a standalone ESXi host.
    Multiple Storage Destinations: backup to local or network share destinations.
    Automated Execution: create backup schedules to automate backups daily, weekly, or monthly.
    Restore Entire VM: restore immediately available VMs from any selected restore points.

    Bind device

    2. Create Backup Task: Navigate to Backup Task > + Create New Task, and select VMware ESXi Backup as the Backup Type.

    3. Set Task Name, Device, Target, Schedule, and Cleanup as needed.

    • Task Name: you can change the task name or use the default name with an ordinal.
    • Device: batch select large numbers of VMs managed by vCenter Server for centralized backup.

    Select virtual machines vCenter

    • Target: select to back up to a local path, or to a network path.

    select backup target

    • Schedule (optional): perform full, differential, or incremental backup, and automate execution according to the frequency you specified.

    schedule VM backup

    • Cleanup (optional): automatically delete the old backup copies that exceed the retention period you specified.

    backup cleanup

    4. Run Backup: Click Start Backup and select Add the schedule and start backup now, or Add the schedule only.

    Start Backup

    Created backup tasks will be listed and monitored separately, for progress checking, schedule changing and restoring. It’s easy to make a clone of a virtual machine in the same or another datastore/host, without reinstalling or configuring a new VM by clicking Restore to new location.
