ejabberd 连接到管理员“缺少服务器”

如何解决ejabberd 连接到管理员“缺少服务器”

我正在尝试配置一个在面向公众的服务器后面工作的 ejabberd 服务。 后者通过Nginx反向代理向前者发送https请求。

访问 https://xmpp.example.cyou:5443/admin/ 时，我为用户 admin 放置了凭据，但无法登录。 日志显示：

2021-07-27 12:12:12.548 [info] <0.396.0>@ejabberd_listener:accept:273 (<0.23212.0>) Accepted connection 44.44.55.55:57850 -> 192.168.7.5:5443

怎么了？缺少什么？

解决方法

我为用户 admin 放置了凭据，但无法登录。

从 > 访问 > 失败，错误：>

您只提供了“admin”帐户，这是错误的。

如https://docs.ejabberd.im/admin/guide/managing/#web-admin

中所述

You will be asked to enter the username (the full Jabber ID)
and password of an ejabberd user with administrator rights.

因此，您必须提供登录凭据：[e-mail] 和密码。
