Add your own secure cert or delete the file and out will start.  Just had

Colin I was supposing you have a zmq endpoint active, hence but it is not. 
So just to check if ntop works run it with the parameter -i eth0 instead 
of the actual -i parameter

Please stop all the ntopng active instances (using ps and kill) 
then run just ntopng like 
# ntopng -i=tcp://127.0.0.1:5556 
-m="10.5.21.0/24,192.168.0.0/16,172.16.0.0/16,150.4.0.0/16" 

Then check the console output and send it to the list in case of issue.

Colin, 

The output suggests that you are you trying to start ntopng in HTTPS. 
Please go through this howto: 
https://github.com/ntop/ntopng/blob/dev/doc/README.SSL 

If that doesn't solve the issue then please enclose: 

- ntopng configuration file or command-line parameters 
- exact ntopng startup command 

You may want to add a -v to the startup command to increase verbosity.

I don't think there is anything bound to this port what is the best way to 
determine this?  I tried the following below.  I also tried to configure 
ntopng to run on a different port but it still failed to start.

Hi Colin, 

If you are trying to start the service, that is the wrong syntax. Have you 
tried running ntopng (with no trailing ./, no parameters) 

I suggest checking out: 
https://github.com/ntop/ntopng/blob/dev/doc/README.ntopng and getting 
familiar with the command line options.

Hi Colin, 

Could you please paste how exactly how you installed and how you are 
running the command?

When trying to start the service it fails 

There is no error message, it simply just says it failed. 

How to I go about trouble shooting this and finding out the reason for it 
not starting.
