CFGR-526 — Hostname/regexp/IP network expected in configuration
Next element of item (named) is of HOST-SET type so a hostname, regular expression for hostnames or an IP address (with or without mask) was expected, but not found.
The error should be probably caused by typing error (check brackets around IP address - '[...]') 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.
