無法通過 Pidgin 在 localhost ejabberd 上註冊新使用者（503：服務不可用）

我在 localhost 上設置了 ejabberd 伺服器，現在可以訪問管理面板localhost:5280/admin

在 pidgin 中，我填寫以下值：

username: root
password: password
host: localhost
resource: 5280  

並檢查“在伺服器上創建這個新帳戶”

我的 mod_register 位於/etc/ejabberd/ejabberd.cfg

{mod_register, [
             %%
             %% After successful registration, the user receives
             %% a message with this subject and body.
             %%
             {welcome_message, {"Welcome!",
                                "Welcome to a Jabber service powered by De$
                                "For information about Jabber visit "
                                "http://www.jabber.org"}},
             %% Replace it with 'none' if you don't want to send such mess$
             %%{welcome_message, none},

             %%
             %% When a user registers, send a notification to
             %% these Jabber accounts.
             %%
             %%{registration_watchers, ["admin1@example.org"]},
             {access, register, [{allow, all}]}
            ]},

當我嘗試註冊使用者 pidgin 時顯示錯誤 503：服務不可用

我哪裡錯了？

我通過其他教程設置了 ejabberd，一切都開始工作了。

sudo apt-get install ejabberd

在 /etc/ejabberd/ejabberd.cfg：

1. 取消註釋行

覆蓋本地 2. 在mod_register配置中：

%% 管理員使用者 {acl, admin, {user, “admin”, “localhost”}}。

%% 主機名 {主機，

$$ “localhost” $$}. 3. 在ACCESS RULES部分：

{訪問，註冊，

$$ {allow, all} $$}. 4. 重啟伺服器：

sudo 服務 ejabberd 重啟
