The port list is not valid. Multiple ports can be entered as a comma-separated list. Port numbers must be in the 0-65535 range. Port ranges (hyphenated) can be entered if the authentication mode is set to "Do not authenticate". The lower limit of a port range must be less than or equal to the upper limit of the port range.
