Nintendo Switch console code 2318-0201: meaning and exact next steps

Model-specific

What is true of this model and not of its siblings

Joining a match

This one is about joining, not dropping.

Status page

Check it first.

Joining a match

This error comes up when the console cannot join an online match, so it concerns the step of connecting to a session, not the quality of a session in progress. Nintendo asks you to check the status page first, since a game server or the matchmaking service may be down.

The connection to the host

Joining depends on reaching the other players or a host, so a restrictive router can block you from some sessions. Restarting the router and creating a fresh internet connection often clears it, and a wired adapter removes wireless doubts.

Timing

Evenings and launch days put heavy load on servers, so a failure that clears an hour later was probably load. If it never clears, collect the date, the game and the code for Nintendo Support.

Joining depends on the host

A match is hosted by a console or a server, and your console needs a clear path to it. A router that filters traffic strictly, or a connection with a restrictive address type, makes some hosts unreachable. Games that report your connection type help here.

Same game, different outcomes

If you can join some matches and not others, the host's connection is a likely factor, not yours. Trying a public match or a different mode shows whether the problem is yours.

Which part is failing

If the console can join some matches but not others, the cause is probably the host or the mode. If it cannot join anything online, the cause is probably your connection or the service. The difference tells you where to look first.

The role of the router

Strict firewalls, parental filters and guest networks can stop a console from reaching a host. Try the console on the main network with filters off for a test match. If it works, adjust the router setting rather than the console.

When to stop trying

If you have joined no match for an hour with several restarts and the status page is clear, stop and try another day. Repeated attempts do not improve the odds, and a fresh start on another day avoids the load that caused the trouble.

A test with a hotspot

Join the console to a phone hotspot for a single match. If it joins, the cause is your home network or router settings, and you should look at filters, guest networks and restrictive settings. If it fails on the hotspot as well, the console or the game's servers are more likely.
