Jabber 11.0 can't automatic login

[Xingxing Zhang]

CUCM 10.5, IMPS 10.5, Jabber client 11.0
Jabber client when manually specify IMPS IP address can be a normal landing,
When set to automatic landing, says "Unable to communicate with the server."
DNS SRV and can be parsed correctly, check the jabber-log.txt found error message on the client pc
[Could not resolve host: CUCM105] HttpClientResult = [UNRESOLVED_HOST_ERROR]
why?

Verify that DNS has been entered correctly with the proper DNS A record. You can use the ping command and use the hostname to verify that your local PC is resolving.

If you can reach it via IP, and not DNS, it is likely a DNS issue.

My local PC use the Ping command can reach CUCM105.XX.com.cn and IMPS105.XX.com.cn.

I made reference to this link, did not solve the problem。
