Environment

VCF Operations 9.1

Cause

Network connectivity is blocked between the VCF Operations and the Log Management, specifically on the required management port TCP 9543.

Resolution

To resolve this issue, ensure the network firewall allows traffic on the following port:

1. Verify connectivity from the VCF Operations nodes to the Log Management nodes.
   
   curl -v telnet://<Log Management FQDN>:9543
   
   
2. Ensure port 9543 (TCP) is open between these components. For example,if the connection is successfully established, you should see the following message:
   
    Established connection to <Log Management FQDN> (<Log Management IP> port 9543) from <VCF Operations IP>
   
   
3. Retry the Log Management installation task in VCF Operations.
