An error occurred during the installation of the VMware Aria Operations plugin in vCenter. The following error message was displayed:
“Cannot complete the operation. See the event log for details. Error downloading plug-in. URL is unreachable. connect timed out.”
Connectivity was tested from the vCenter to the Aria Operations appliance using the curl command:
curl -v https://<Aria operations FQDN>:443
* Trying <IP address>...
* TCP_NODELAY set
* connect to <IP address> port 443 failed: Connection timed out
* Failed to connect to <hostname> port 443: Connection timed out
* Closing connection 0
curl: (7) Failed to connect to <hostname> port 443: Connection timed out
Aria Operations 8.x
The plugin installation failed due to a network connectivity issue. vCenter was unable to reach the VMware Aria Operations appliance over port 443 (HTTPS).
Ensure that port 443 (HTTPS) is open between the vCenter Server and the VMware Aria Operations. This port must be accessible to allow secure communication required for downloading and installing the plugin.
For full port requirements, refer to the VMware documentation:
