Softphone (X-lite) can't register to pbxnsip

[pbxnsip newb]

Does anyone have any issue registering X-lite softphone (version 3.0 build 41150) to pbxnsip (version 2.1.0.2115 (Win32))? My X-lite sofphone returns Registration Error 404 - Not Found when failed to register. X-lite connects and works ok when config to connect to proxy server/softswitch directly. Tried download a different softphone program and can't register to pbxnsip as well. I probably am missing something in the pbxnsip setup for this not to work? But I have set up another extension connecting to a Snom IP phone and it works fine. I am out of idea how to get this to work, does anyone have any advice? Thanks!

Do you have a domain name called "localhost"? Does the account that you are trying to register there exist? Do you see the REGISTER request in the log when you turn the log level to 7 and enable logging of REGISTER messages?

I was using domain with different name, not the default "localhost" (was deleted). I re-created the "localhost" domain after reading your response and now everything is working ok, issue resolved, thanks! Had a question though, why/how is this sensitive to domain name "localhost"?

Well, that was inspired by the Unix DNS entry for the host itself. Maybe it would have been better to choose a name like "any", "anyhost" or maybe "anydomain" or "whatever". But now it's too late to change something like that...
