在Photon Server的WebHooksPlugin發生錯誤時的處置方法

錯誤的發生原因

原因可能與Photon Server功能之一的外掛程式正在執行有關。在Photon中，伺服端邏輯可使用外掛程式進行開發。預設中允許執行範例程式「WebHooksPlugin」。有可能是因為WebHooksPlugin所連結的目標 http://photon-photon-pluginsdk-v1.webscript.io/GameCreate 發生問題，才導致此次的錯誤出現。

修正方式

將Photon.LoadBalancing.dll.config的WebHooksPlugin取消即可解決。
請將PluginSettings Enable設定為false。
為防萬一，請將Master/Game兩方的伺服器均設定為無效較為妥當。

如下所示：
<PluginSettings Enabled="false"> 
<Plugins> 
<Plugin 
Name="WebHooksPlugin1.2"
