I hate that error message - its just about the most useless
one out there. Not exactly sure what could be the problem if your
current host and your new host environment are identical. You could
try troubleshooting the following:
1) If you are moving from windows -> linux hosting it
could be an issue with case sensitivity
2) If you can remote connect to your new hosting box, try
connecting to the WSDL's using a browser to make sure there isn't
anything blocking your connection
2a) If you don't have access to the box, try performing
CFHTTP calls to the WSDL's instead.
3) Make sure the WSDL locations are refreshed in the CF
administrator (if you are using shared hosting, its possible that
someone else tried to connect to an older version of the
webservices and the CF webservice wsdl definitions are cached on
your machine)
4) Check with your hosting provider to see if you need to use
a proxy server for webservice calls from your server.
I know that's not incredibly helpful, but hopefully one of
those will point you in the right direction.
