Failed to get local InetAddress for VMID. No idea what it means

Hi.

I'm getting this weird error, I have no idea what it means. Could any of you be kind enough and explain at least where should I check the problem from? The only bug within the server is that the day and night cycles don't switch. Whenever I set it day, for example, the sun rises for 5 seconds and then falls back to dawn and it continues like this forever.

Code:

2012-02-09 17:58:49 [INFO] Failed to get local InetAddress for VMID. This is unlikely to matter. At all. We'll add some extra randomness

I get the same error with EssentialsProtect running, if I remove EssentialsProtect the error goes away. Funny thing is this started happening after I moved to a data center for hosting. I removed the Essentials folder and allowed server to re-build, still get the error. I downloaded all files to my home computer, launch server and no error. I think it has something to do with the configuration of a the server. :/

Unfortunately, I found a couple other threads on this topic but no solutions.

 

Aha, let me guess.. Theres a auto port forwarding plugin in there?

If not, you must state an ip (external) in the server properties
