Database connection is not available.

I'm using Hana Studio to connect to Hana SP4(SUSE Linux Enterprise VM), I could ping Hana IP successfullly (192.168.0.30), but could't ping it's host name. When addding system, got "Database connection is not available. "

I checked Hana sever is avaialbe, HDB info. I Can also use putty to connect to Hana, my concern is why can't ping Hana's hostname, is that the reason why failed to connect to Hana Sever?

Any feedback is appreciated, thanks for your time.
