我已经在服务器中安装了Ejabberd版本17.11。安装后，用户将能够第一次成功连接到Ejabberd服务。但是，一旦会话由该用户结束，并且如果同一用户尝试再次连接，则我们将收到以下错误消息。
websocket | <0.574.0>）来自xx.xx.xxx.xxx的user @ domain的c2s PLAIN身份验证失败：无效的用户名或密码
注意： 在用户关闭会话时，我们得到以下消息。那是为什么同一用户第一次无法连接吗？
（websocket | <0.534.0>）正在关闭user @ domain / reg_agent的c2s会话：连接失败：连接已关闭 [info]删除任何user @ domain的推送会话
答案 0 :(得分：0)
[info]删除任何user @ domain的推送会话
查看源代码文件mod_push.erl，在删除帐户时会记录该消息。
因此，由于某种原因，该帐户已被删除。如果使用匿名身份验证，则注销帐户时将其删除。如果您使用内部或SQL身份验证，则应检查已启用的其他模块，这些模块可能会在注销时删除帐户。

在.yml配置文件中添加以下行后，现在可以正常使用了。
auth_use_cache：false
此外，还有一件事-我们可以使用bosh方法代替较低版本中使用的http_bind方法吗？对于较低版本的浏览器和iPad应用程序，我们均使用此http_bind方法，而这些浏览器和iPad应用程序均不支持WebSocket功能。
