After completing VMware vCenter server appliance (vcsa) installation and configuration, when tested vCenter UI url https://vcenter:443/ui, I was receiving below error. I restarted vCenter server vcsa multiple times, checked if DNS entries (A host record and PTR pointer record) exists in DNS server for vCenter server, but this error didn't go away.
no healty upstream
To resolve the issue further I checked all the services status, under vCenter server management 5480 vami portal, Restarted couple of services, Checked server health in Monitor, all was good, but still no luck.
Next I found one of the settings which I configured and documented in Unable to save IP settings Install Stage 2 Set up vCenter Server configuration where I had configured vCenter server to obtain IP address from DHCP. I reverted IP address setting from DHCP to static with below steps. Before making any changes make sure you backup vCenter server or take snapshot.
Log in to VMware Server Managment vami portal with 5480 port, go to Networking section and click EDIT. I have only one network adapter and it already selected, click Next.
In the Edit Settings change the setting from Obtain IPv4 settings automatically to Enter IPv4 settings manually and click Next button.
Provide SSO administrator credentials for vCenter server click Next button. (Username: [email protected]).
In last, Ready to complete page verify the settings to be done. Click the checkbox to acknowledge that you have made a backup of your vCenter server and unregistered extensions before continuing with your network configuration.
After network settings have been reconfigured and your vCenter server is up and running, additional actions will be required.
1. All deployed plug-ins will need to be reregistered.
2. All custom certififcates will need to be regenerated.
3. vCenter HA will need to be reconfigured.
4. Hybrid Link with Cloud vCenter server will need to be recreated.
5. Active Directory will need to be rejoined.
Click Finish button.
Avoid refreshing your web browser to ensure a successful network upgrade. Once update is 100% completed close the window and test vCenter server url https://vcenter/ui. All looks good.
If you want to change the same gui setting through vCenter Server SSH. Open shell and change DHCP=no in the file /etc/systemd/network/10-eth0.network as shown on Unable to save IP settings Install Stage 2 Set up vCenter Server configuration.
Enable Access to the VCSA Bash shell or Appliance Shell
