Issue/Introduction
Unable to Upgrade vCenter from 7.0.X to 8.0.X.
Stage 1 completes without issue and the new appliance is deployed successfully.
During the stage 2 prechecks, the following error is shown:
Failed to connect to the source vCenter Server or ESXi container <vCenterName> port 443: [Errno 111] Connection refused
Clicking on the Logs Button shows, "Failed to Download Logs"
Not able to navigate to the page at https://new_ip_address:5480 without issue.
Environment
vCenter 7.0
Cause
This is due to connectivity issues between the installer and the newly deployed vCenter appliance.
Resolution
Run the following command:
curl -v telnet://VC FQDN:port number
If this command fails:
curl: (7) Failed to connect to <FQDN> port 443 after #### ms: Couldn't connect to server
Have the customer engage their networking/firewall team to resolve the connection issue.
