A “Connection refused” (code 111) error on EPP port 700 means your server cannot reach the registry at registry.nic.net.ng, usually due to a blocked port or an unwhitelisted server IP. [1, 2]
Common Causes & Fixes
  • IP Whitelisting: Registries like NiRA (nic.net.ng) require your server’s outgoing IP address to be explicitly whitelisted in your registrar/registry account profile. If the IP is unrecognized, the connection is actively refused. [1]
  • Firewall Restrictions: Outbound traffic on TCP port 700 might be blocked by your host’s firewall or network configuration. [1]
  • Incorrect EPP Host/Endpoint: Ensure the registry environment (sandbox/test vs. production) matches your configuration and that port 700 is specified correctly.
Recommended Steps
  • Check Whitelist: Log into your NiRA/registry account and verify your current server public IP is added to the allowed EPP access list.
  • Test Outbound Port: Run a command like nc -zv registry.nic.net.ng 700 or telnet registry.nic.net.ng 700 from your server terminal to see if the network path is open.
  • Contact Hosting/Registry: If the port times out or refuses and your IP is correct, ask your hosting provider to ensure outbound port 700 is open, or contact NiRA support. [1]
