AutoSSL Issue, Pending for more than 6 days

Hello,
AutoSSL does not work in my WHM, I copied the log message below:

Code:

----------------
 3:19:38 PM This system has AutoSSL set to use “cPanel (powered by Comodo)”.
 3:19:38 PM Checking websites for “user” …
 3:19:38 PM The website “domain.cn”, owned by “user”, has a faulty SSL certificate (OPENSSL_VERIFY:0:18:DEPTH_ZERO_SELF_SIGNED_CERT NOT_ALL_DOMAINS). AutoSSL will attempt to replace this certificate.
 3:19:39 PM The system will attempt to renew SSL certificates for the following websites:
 3:19:39 PM domain.cn (domain.cn www.domain.cn mail.domain.cn webmail.domain.cn cpanel.domain.cn webdisk.domain.cn)
 3:19:39 PM The system has completed the AutoSSL check for “user”.
----------------

I found tow records in "Pending Queue":

Code:

-----------------
www.domain.cn domain.cn user Jul 28, 2017 5:17:01 PM 223570023 Pending
domain.cn domain.cn user Jul 28, 2017 5:17:01 PM 223570023 Pending
----------------- 

I replaced my domain and user name.
Everyone can tell me, how can I fix the issue?
Thanks for advice,
