通过验证码进行XMPP注册-失败，响应<错误代码=“ 405” type =“ cancel”>验证码注册

如何解决通过验证码进行XMPP注册-失败，响应<错误代码=“ 405” type =“ cancel”>验证码注册

我尝试通过agsXMPP lib向验证码注册。我将这样的XDATA发送到服务器：

"<instructions xmlns=\"jabber:x:data\">Choose a username and password to register with this server</instructions><field xmlns=\"jabber:x:data\" type=\"hidden\" var=\"FORM_TYPE\"><value>urn:xmpp:captcha</value></field><field xmlns=\"jabber:x:data\" label=\"User\" var=\"username\" type=\"text-single\"><required /><value>victorsps</value></field><field xmlns=\"jabber:x:data\" label=\"Password\" var=\"password\" type=\"text-private\"><required /><value>a25160920</value></field><field xmlns=\"jabber:x:data\" type=\"fixed\" var=\"captcha-fallback-text\"><value>If you don't see the CAPTCHA image here,visit the web page.</value></field><field xmlns=\"jabber:x:data\" type=\"hidden\" var=\"captchahidden\"><value>workaround-for-psi</value></field><field xmlns=\"jabber:x:data\" label=\"CAPTCHA web page\" var=\"captcha-fallback-url\" type=\"text-single\"><value>http://jabber.freenet.de/captcha/13382908590620806174/image</value></field><field xmlns=\"jabber:x:data\" type=\"hidden\" var=\"from\"><value>jabber.freenet.de</value></field><field xmlns=\"jabber:x:data\" type=\"hidden\" var=\"challenge\"><value>13382908590620806174</value></field><field xmlns=\"jabber:x:data\" type=\"hidden\" var=\"sid\"><value>agsXMPP_1</value></field><field xmlns=\"jabber:x:data\" label=\"Enter the text you see\" var=\"ocr\" type=\"text-single\"><media xmlns=\"urn:xmpp:media-element\"><uri type=\"image/png\">cid:[e-mail]</uri></media><required /><value>145957</value></field>"

但是注册失败，服务器向我发送了这样的回复：
