我正在使用FOSUserBundle
with Symfony2
,几天前注册过程运行良好,然后在注册时突然出现以下错误:
Expected response code 220 but got code "421", with message "421 Cannot connect to SMTP server x.x.x.x (x.x.x.x), connect error 10061
500 Internal Server Error - Swift_TransportException
"
和 :
x.x.x.x stands for smtp IP adress
它与smtp有关。知道如何解决这个问题吗?
