Syslog Error after the server lost connection in unRAID beta 6

I’ve been using unRAID Server since Beta 5 and the AD combination works just fine (other than the periodic lost permissions). But due to some circumstances today, the server lost connection with AD and keeps getting this error in syslog whenever I try to get it to join:
"Jan 5 13:42:16 Tower logger: Failed to join domain: failed to lookup DC info for domain 'XXXX-XXXX.COM' over rpc: Logon failure
Jan 5 13:42:24 Tower logger: Failed to join domain: failed to lookup DC info for domain 'XXXX-XXXX.COM' over rpc: Logon failure
Jan 5 13:42:33 Tower logger: Failed to join domain: Failed to set account flags for machine account (NT_STATUS_ACCESS_DENIED)”
The XXXX-XXXX.com is our FQDN. I’m running unRAID beta 6 when this happened and then updated it to beta 8 without changing anything in the configurations. Any of you have ideas regarding this matter? If so, then please help me.
