Environment:
Spectrum OneClick any version running on Linux
Cause:

The TCP/IP port numbers below 1024 are special on Linux in that normal users are not allowed to run servers on them. This is a security feature, in that if you connect to a service on one of these ports you can be fairly sure that you have the real thing, and not a fake which some hacker has put up for you. 

Resolution:

Although the Linux administrator can configure normal users to be able to run on TCP/IP port numbers below 1024, it is not recommended.

It is also not recommended to run Spectrum OneClick as the root user.
