Communications error

"A communication error has occurred. If this error persists, it may be due to your connection being unstable. For more details, please visit the Nintendo Switch support site."

- 's alternate communication error message.



A communications error, commonly referred to as a communication error, occurs in the Splatoon series when players in an online match become unable to connect to the other consoles due to issues with one or more player's internet connections. It results in the forfeiture of the current match.

Background
In the Splatoon series, a central server is only used for the initial connection and matchmaking purposes, after which participants are connected to each other via peer-to-peer communications.

In the event that the network connectivity of a player is interrupted for whatever reason, even partially or temporarily, their participation in a match is adversely affected. Many pieces of information are transmitted between players at all times, including player and objective locations and ink behavior. Should the information get processed out of order, or should any console delay in sending the information to others, anomalies such as turf not being inked when shot or players appearing to teleport around can occur.

It is possible for multiple players to have communication problems simultaneously; if communication across the entire match suffers enough, it may forcibly end for all players. When this occurs, the message "A communications error occurred" or the message "A communication error has occurred" appears, and the player returns to the Battle Lobby.

Splatoon 2


In Splatoon 2, receiving multiple disconnects in a short amount of time may block players from participating in online play for a period of time. The first couple of disconnections yields a warning message when attempting to join a match.

After multiple disconnections, the player is temporarily blocked from online play for five minutes, where the following is displayed:

"Your previous online play session didn't end naturally, so we're gonna have to drop the hammer on ya. Make sure your Internet isn't messed up, and try again in (insert number) minute(s)."

- Message displayed when blocked from online play after disconnecting.

As of Version, players who have frequent disconnects may get punished for an extended time period of 15 minutes, 30 minutes, or even 60 minutes. If all players are affected by the error, they generally do not get this ban.

Players will also get banned from play immediately if the mid-match disconnect was intentional (i.e. Nintendo Switch system set to sleep, the game being shut off, or when disconnected by idling), or if the game crashed unexpectedly before then.

In addition, players may report other players for disconnecting using SplatNet 2 and said players may be banned for longer periods of time as a result.

Splatoon 3


Like in Splatoon 2, players will receive a ban after multiple disconnects, albeit with the ban timer starting at ten minutes. However, it is more likely for players to get disconnected; at most times (if the player(s) have a good connection) these errors are most likely Nintendo's servers failing, or another player's internet connection. In rare cases, a mass of players disconnect at the same time, or one after another, usually indicated by Inkrails that stop working until all players disconnect, or when the timer does not end the game until all players disconnect; the reason why this happens is that the "host" player disconnected, causing the connection to become very unstable to many players due to the game having difficulty trying to migrate the host to another player.

Additionally, if a player disconnects within the first minute of a public match, the game will end after ten seconds (unless a Knockout occurs during an Anarchy Battle within the time frame), presumably to prevent games from being one-sided early on. When this happens, the following is displayed:

"One or more players disconnected shortly after the battle began. Disconnected players will be assigned a loss, but the battle will not count for players who remained connected."

- Message displayed after a first-minute disconnect.

The match will count as a draw for all players that remained connected, and no one will receive any rewards. No battle replay will be saved in this scenario.

Effects of disconnection
Should a player be disconnected in the middle of a match due to a communications error, they are returned to the Battle Lobby, and the following actions are taken.

For the disconnected player, the following applies:


 * In both Regular Battles and Ranked Battles, Vibe or Freshness is deducted and the match is considered a loss
 * In Ranked Battles, points are deducted based on the player's rank and team composition.
 * In Anarchy Battle (Series) if the player is disconnected one loss will be added to the player's run
 * In Salmon Run and its successor, the player is penalized as if they had lost in the first wave regardless of which wave they were on when the disconnection occurred. Therefore, their Job Title's point range is reduced by twenty points and will not earn Grizzco Points.

In, for the teammates playing with a disconnected player, the following applies:


 * In Regular Battles, teammates do not lose Freshness if the player was disconnected early in the match.
 * In Ranked Battles, teammates do not get a crack in their rank meter if the player was disconnected early in the match.
 * In Splatfests, teammates did not lose their Splatfest Power if the player was disconnected early in the match.
 * In Salmon Run, teammates would receive half the normal pay cut if they lose in the corresponding waves if the player was disconnected at any wave in the match. For example, they would lose ten points in Wave 1 and five points in Wave 2. The Golden Egg quota also re-balances itself to accommodate for fewer players, though the rate at which Salmonids spawn is unaffected by this.

In, if a player disconnected mid-match, any connected players on the losing team will not have their match count as a loss. However, a bug in Version 1.1.0 prevented said players from earning cash or XP as a result, though strangely, Catalog XP would still be awarded. Also, if a disconnect occurs during an Xtrawave in Salmon Run, the King Salmonid's HP will be reduced by 25% of its normal amount.

Another bug treats player's disconnects as regular disconnects, but does not give a penalty of 10 minutes.

Occasionally, a completed match in Splatoon 3 may fail to save properly to certain players, flagging their match as if they had disconnected, but would still earn Catalog XP. This can be indicated by the delay that occurs during results before the "Game saved!" indicator appears on the bottom left corner of the screen.



When a player disconnects, the post-match scoreboard shows them with 0p of turf inked (unless the game ended in a draw in Splatoon 3), excluding any win bonuses. However, their correct number of splats, specials, and deaths is still displayed. In-match, players who disconnect disappear in a puff of smoke and do not respawn. In Salmon Run, the disconnected player's character is completely absent from the results screen.

In, the player that got disconnected shows in the user interface as being permanently splatted, having a dark squid icon with crossed-out eyes. In Splatoon 2, the disconnected player has an X over their icon while their weapon remains colored instead of being grayed out like it normally would be. In Salmon Run, the disconnected player has a gray blank icon, while a splatted player has an Icon matching a disconnected player in other modes. In a disconnected player has a completely blacked-out icon, with nothing on it. In addition, their splats and deaths will not be displayed on the results screen.

Solving the problem
Any form of a networking issue may result in a communications error. Problems may occur on the user's end, such as wireless interference or lack of available bandwidth due to other devices on the network; problems may also be due to outages or disruptions at the level of an Internet Service Provider.

If receiving communications errors while playing the Splatoon series online, it is advised to close high-bandwidth applications such as video streaming services or large file downloads.

The use of a wired LAN adapter is the most effective way to improve the connection and thus reduce the chance of communications errors. Nintendo sells an official Wired Internet LAN Adapter and third parties sell functionally identical adapters that are compatible with Nintendo consoles. If a wired access point is not near the console, it is still possible to obtain a wired connection by using powerline Ethernet adapters to add a wired access point nearby.

There are several ways to improve wireless connections. The most effective way is to switch to a 5 GHz WiFi band. The 5 GHz band is available on all relatively recently made home wireless routers. The 5 GHz band allows for a faster, more stable connection than the other WiFi band, 2.4 GHz. The 5 GHz band may need to be enabled in the router's configuration menu, and once enabled, the WiFi password may need to be re-entered on the console. Ensuring a NAT type of A or B may improve wireless connections because this essentially indicates a status of allowing incoming connections to reach the device without being blocked by security measures. The option to change the NAT type should be available in the wireless router's configuration menu.

Side effects



 * Delay in ink appearing on the stage.
 * Lagging or teleporting players.
 * Frozen players.
 * Players displayed as being splatted by far-away opponents.
 * Delayed "Splatted" message after splatting a player.
 * "The connection is unstable." message.
 * When this message appears on players' screens during a match, players cannot move. Animations, such as firing weapons, may continue to play. Any players that are on Inkrails will also be automatically switched into kid form, therefore causing the player to fall off the Inkrail.
 * In, a disconnect that occurs after "The connection is unstable" message often occurs in the following manner, from the view of a disconnected player, all other players will disconnect except for one. The remaining player will be frozen in an animation loop, and cannot be splatted. The disconnected player can still walk around the stage for a short while before they are booted back to the lobby.

Trivia



 * It is possible to disconnect even if the internet quality is good. Players who are away from their controllers for sixty seconds automatically disconnect.
 * Splatoon 2 and Splatoon 3 both recognize this as an intentional disconnect and thus will force an automatic ban when available. In the latter, since online play data is tied to the associated Nintendo Account, the "Game saved!" indicator does not appear on the bottom left of the screen.
 * Sometimes, if the player is still in the Battle Lobby and is on other networks (for example, on the Wii U Internet Browser or the Nintendo Switch Album), the communication error message appears.
 * There used to be a bug in Splatoon 3 where the game may crash when receiving a communication error during Salmon Run matchmaking or when attempting to reconnect to the Internet via Grizzco Industries after a loss of connection to the server during a shift, but was patched in Version 2.0.0 without being listed in the patch notes.
