yes, it was happening to my server exactly what is happening to yours

sure, the file is /etc/hosts. try to put your real ip here too, and
replace the name 'yourserver.yourdomain.com' and 'yourserver' with
your machine real name
example:
127.0.0.1 localhost.localdomain localhost
10.1.1.1 yourserver.yourdomain.com yourserver

I remember now this issue can also be related to fix/dynamic ip
addresses. Does your server have a dynamic ip address, assigned by a
dhcp server? If yes, try to fix it, too.
