Intro

Your SCP: Secret Laboratory server is running, but nobody can find it in the list? Here's the fix.

Verification

To appear in the browser, your server has to verify with the official central server. If verification fails, the server still runs, but it stays hidden.

Port 7777

The most common cause is a closed port. The game uses a single UDP port, 7777 by default. The central server tests it from outside, so open and forward it.

Startup console

Then read the startup console. It tells you whether verification succeeded, and why it failed.

Other causes

Other causes: an outdated server build after a new release, a second server already using the same port, or a crash right after boot, before verification even starts.

Direct connect

While you sort out the listing, players can still join directly, with your server IP and port 7777.

Recap

Open the port, update the server, read the console. SCP: Secret Laboratory hosting at esagames.ro.
