SPsite returning access error for an url different than the called one

Question

I wrote a small C# .Net 4.5.2 application to rename some doc libraries. It fails at the very beginning:

using(SPSite sitecoll=new SPSite("http://192.168.0.14:8069"))

with the message

Web application at http://localhost cannot be found

• The same app in the dev server runs fine, but there sharepoint is mapped to http://localhost.
• The same commands issued via powershell run fine.
• Sharepoint is totally accessible both locally and remotely via VPN, and I'm running the application as a sharepoint/site administrator.
• I also tried using the machine name http://sharepoint:8069 and http://localhost:8069

• I get slightly different errors running from the dev machine, remotely via VPN, in this case the URL is reported correctly:

  The web application at http://192.168.0.14:8069 cannot be found

UPDATE I even tried a non-existing name, http://foo:8069, and I get the same reply! Any advice? Thank you

Solved

It was a matter of security and permissions: I solved by running the code with

var elevata = new SPSecurity.CodeToRunElevated(
               delegate () { myCode(); });
SPSecurity.RunWithElevatedPrivileges(elevata);
