What is the host in question? Could it be resolved externally, or you have it configured through your hosts file, or local DNS server?

There are a lot of network-related and java-related possible causes of the "communications link failure" error: 

https://stackoverflow.com/a/10772407/8203759

Let's start from the following: 

Add 

-Djava.net.preferIPv4Stack=true

into the idea.vmoptions file (Help | Edit custom VM options)

If it does not help, share the whole idea.log (Help | Collect Logs and Diagnostic Data)

Also, it could be DNS cache issue.

Try the following workaround:

The Java virtual machine (JVM) caches DNS name lookups. When the JVM resolves a hostname to an IP address, it caches the IP address for a specified period of time, known as the time-to-live (TTL).

To modify the JVM's TTL, set the networkaddress.cache.ttl property value for you data source settings advanced tab
-Dnetworkaddress.cache.ttl=60

I cont upload a logs file,so copy some logs :

in the log can find those config,but still fail

-Djava.net.preferIPv4Stack=true
-Dnetworkaddress.cache.ttl=60
