Hello

I'm changing my web host, I was on a shared server and I'm now on a vps in a different company. I tried to import the data from my test forum (3.6.5) to a clean install of vbulletin 3.6.5

But everytime I click the import link in my admincp I get this error:

Code:
Connection to source server failed. Check username and password
I know everything is ok in my impex config file, my previous host used "hostname.site.com" and my new host uses "localhost", could that be the reason my import is failing?

this is my first vps, and don't know much about databases, hostnames, and so on, but I'm learning, sorry if my question is silly

thanks in advance
