Send connector to internet is broken. No Matching Connector.

I don't know why, but connector to external * hosts today is broken, but yesterday was working fine. Yesterday I change site of MBOX and setup CU2. Now all messages in Message Queuing with error: No Matching Connector. I tryed recreate Send Connector and reboot MBOX server.. tryed change external DNS in MBOX.. but still No Matching Connector. Whats wrong?
