Your server is running, the Console is happy - but nobody can find or join it. These are the usual suspects.

Not appearing in the server list

sv_master1 is disabled

Make sure server.cfg does not contain:
That line takes the server off the public list. Remove it (or comment it out) and restart.

sv_listingHostOverride mismatch

If you set sv_listingHostOverride, it must point to the public IP and port shown in Network. A mismatch silently hides the server from the master list.

endpoint_add_tcp / endpoint_add_udp port conflict

FiveM’s default port is 30120. If you leave that hardcoded in server.cfg, you’ll collide with another FiveM server on the same node and your server either won’t bind or won’t be reachable. You can leave the IP as 0.0.0.0 (it just means “bind to all interfaces inside your container”), but the port must match the game port shown in Network:
Replace YOUR_PORT with your assigned game port - not 30120.

Onesync / hostname not set

The master list rejects servers missing required convars. Confirm server.cfg has:
Setting sv_maxclients above 10 without a Cfx server key / Element Club subscription can cause custom clothing (and other custom streamed assets) to fail to load for players. If you’re not licensed and want more than 10 slots, expect missing or default outfits. Grab a key from keymaster.fivem.net before scaling up.

Players get “couldn’t connect”

Wrong port shared

Double-check players are using the game port, not the txAdmin port. Both are listed in Network - the alias should make it obvious.

Player banned by the master list

That’s a Cfx-level ban, not us. The player needs to appeal through Cfx.

Server full / queue stuck

If you use a queue resource (e.g. connectqueue), a buggy update can lock the queue. Check its console output and restart the resource.

High ping or rubber-banding

  • Confirm the player is connecting to the closest datacenter (Dallas or Miami). If they’re on the wrong coast, route is the culprit.
  • Check live CPU on the Console. If CPU is pegged, a resource is hot-looping - narrow it down with resmon in-game.
  • Run a traceroute from the player to your server IP and send us the output if you suspect a network issue.

Still stuck?

Grab the server IP/port and a screenshot of the connection error and open a ticket.
