Actionscript Error #2044: Unhandled SecurityErrorEvent:. text=Error #2047: Security sandbox violation: LocalConnection.send: 127.0.0.1 cannot access

Question

When running flash components that use localConnection within an HTML container, I get the following error in a popup box (flash player is the debug version):

Error #2044: Unhandled SecurityErrorEvent:. text=Error #2047: Security sandbox violation: LocalConnection.send: 127.0.0.1 cannot access

Answer 1

Changing the page's URL from http://127.0.0.1/ to http://localhost/ solved the problem.

Answer 2

// add this line after the instanciation aof the receiver file

receiveSwf_lc.allowDomain("localhost");

// or whatever domain you like, use * as wildcard to allow any domain name
