Expected Behavior:

A server should not start without Public IP.

Steps To Reproduce:

Slack (for internal team)

Note:

Investigate why the server is getting started without ip even when ip is available which is being set for Outbound IP and fix if possible and error handling to not start server without public ip.

This issues results into downtime of public interactsh server - https://status.projectdiscovery.io
