If you do not define localhost as the loopback address, the Endpoint Operations Management agent does not register and the following error appears: Connection failed. Server may be down (or wrong IP/port were used). Waiting for 10 seconds before retrying.
About this task
As a workaround, complete the following steps:
- Open the hosts file /etc/hosts on Linux or C:\Windows\System32\Drivers\etc\hosts on Windows.
- Modify the file to include a localhost mapping to the IPv4 127.0.0.1 loopback address, using 127.0.0.1 localhost.
- Save the file.
Endpoint Operations Management agent does not support IPv6.
