簡介
本文描述如何在使用Join（加入）按鈕時對「Cloud Devices failed to join a Webex Meeting」(雲裝置無法加入Webex會議)進行故障排除。
問題
嘗試使用Join按鈕加入Webex會議時，系統會顯示以下消息：
「無法加入會議。會議號碼無效。請檢查號碼或連結，然後重試。」
疑難排解
在裝置日誌中定位故障嘗試
在日誌套件組合中找到callhistory.txt。

根本原因
加入會議問題的根本原因是會議系列被主持人刪除或取消。已成功分析預訂資訊並顯示在裝置上，但在使用Join按鈕時，後端返回了404錯誤。
解決方案
重新安排新會議，並確保分配給裝置的郵箱接受並正確更新新會議詳細資訊。
