CFGR-528 — Hostname/IP address not followed by a colon
Next element of item (named) is of SOCK type so behind the host name/address a colon and port number or name was expected, but not found.
The error should be probably caused by typing error, misspelled hostname or by incorrect order of elements used. See application section 5 manual page for description of correct syntax of item.
Application cannot be configured and it will fail.
