Getting wrong hostname on web-interface

[Tafsir_Alam (Tafsir)]

Hi,

I am using the latest version of graylog 3.1.2 and after setup I found the GL Nodes picking the wrong hostname.
I checked the hostname on the server and its correct but showing incorrect name on the graylog web-Interface. Not sure if I am missing something or not.

Elasticsearch Version - 6.8

Web-Interface Output

Server Terminal Output

A quick response will be appreciated.

Thanks

it looks like the system can resolve the given configuration (IP wise) to this hostname.
