フレンドがすでにValheimの世界を冒険しているのに、自分だけ「接続に失敗しました」と表示されてワールドに入れない……。このエラーの原因は1つだけではないため、順を追って原因を特定していく必要があります。
このNitradoガイドでは、サーバーの稼働状況の確認からコンソール版プレイヤー向けのクロスプレイ設定まで、エラーの解決手順をわかりやすく解説します。最初の6項目はPC環境向けの対処法です。コンソールから参加している方は、後半のクロスプレイに関する章をご確認ください。
参加者全員に同じエラーが発生する場合は、まずサーバー側の状態を確認しましょう。Nitrado Web Interfaceを開き、ダッシュボードのプレイヤー数横にある「サーバー状態」を確認します。サーバーが停止している場合は起動し、再起動が完全に完了してから再接続を試みてください。

ゲームファイルの一部が不足・破損している場合もエラーが発生します。SteamからValheimのファイルを検証しましょう。ライブラリでゲームを右クリックしてプロパティを開き、ローカルファイル(またはインストール済みファイル)タブからゲームファイルの整合性を確認を選択します。破損が検知された場合、Steamが自動的に修復を行います。

古いネットワークドライバーが原因で接続がブロックされることがあります。Windowsのデバイス マネージャーを開き、ネットワーク アダプターの項目を展開して、使用しているネットワークカードのドライバーを最新状態に更新してください。しばらくドライバーを更新していない場合に有効な対処法です。
ルーターはインターネット接続全体を管理しているため、再起動によって接続エラーが解消されることがあります。ルーターの電源プラグを抜き、30秒ほど待ってから再度コンセントに差し込み、Valheimサーバーへの接続を再試行してください。
Windows標準の機能やセキュリティソフトのファイアウォールによって、Valheimの通信がブロックされている可能性があります。ファイアウォールの許可リストにValheimを追加してください。具体的な設定方法は、お使いのセキュリティソフトの公式ヘルプをご確認ください。
DNSのキャッシュクリアを行うことで、ルーターの再起動と同様にPC内のネットワークアドレス情報がリセットされます。コマンド プロンプトを管理者として実行し、ipconfig /flushdns と入力して実行してください。PC内の他のデータに影響を与えることはありません。
コンソール版の登場に伴い、「接続に失敗しました」エラーの主な発生原因も変化しています。コンソール版やMicrosoft Store版のプレイヤーが参加できない一般的な原因とその解決策を紹介します。
Valheimの専用サーバーはデフォルトでSteamのシステムを使用しているため、Steam限定設定のサーバーはMicrosoft Store、Xbox、そして2026年9月9日の1.0正式リリース時点で対応するPlayStation 5およびSwitch 2のプレイヤーからは検索できません。Web Interfaceの 設定 > 一般 にある クロスプレイ (Crossplay) を有効化して保存し、サーバーを再起動することで、他プラットフォームのプレイヤーもサーバーを検索して参加できるようになります。
クロスプレイ設定の変更後、Valheimのマスターサーバーが情報をキャッシュする関係で、公開サーバー一覧への反映に少し時間がかかる場合があります。参加コード(Join Code)やIPアドレスを直接入力する方法であれば即座に参加可能ですので、一覧に表示されるまではそちらの情報を共有してください。

サーバーが再起動するたびに参加コードは新しく更新されます。そのため、昨日使えたコードを今日そのまま使用することはできません。Valheimサーバー内でポーズメニューを開き、最新のコードをコピーしてフレンドに再度共有してください。
Valheimでサーバーに接続するには、クライアントとサーバーのバージョンが一致している必要があります。2026年9月9日の1.0正式リリースのような大型アップデート時には、全プレイヤーのバージョンが一斉に変更されます。お使いのゲーム本体のバージョンと、Web Interfaceのダッシュボードにある「バージョン」表示を比較してください。一致していない場合はValheimのバージョン不一致エラーが発生します。サーバー側のアップデート完了を待ってから再接続してください。
サーバーの稼働、ドライバーの更新、コンソール向けクロスプレイの設定が完了すれば、準備は万全です。最新の参加コードを共有して、みんなで一緒にValheimの世界へ飛び込みましょう!
以下の確認を順に行ってください:サーバーの稼働状態の確認、Steamでのゲームファイルの整合性チェック、 networkドライバーの更新、ルーターの再起動、ファイアウォールでの通信許可、DNSキャッシュのクリア。コンソールやクロスプレイで参加する場合は、クロスプレイ設定が有効か、参加コードが最新かも合わせて確認してください。
PC版では、ゲームファイルの不足や破損、ネットワークキャッシュの古い情報、一時的な回線問題が主な原因です。コンソール版や異なるプラットフォーム間でのプレイ時には、クロスプレイ設定の無効化、有効期限切れの参加コード、アップデート後のバージョン不一致によりエラーが発生します。
サーバーがオフラインまたは再起動中である、パスワードが設定されている、ホワイトリストが有効化されている、あるいは参加者が導入していないMODがサーバーに入っている可能性が考えられます。1つずつ設定を確認してみてください。解決しない場合は、Nitradoのサポートチームへお問い合わせください。
