Error with Mongoose Web Server : failed to open listener

[Keshava Kumar]

Hi SWUpdate community. 

I am testing SWUpdate with Yocto Build on my custom i.MX8QM board. 

I am using dual copy method and was successful in copying to standby copying using local update method. 

Now I am trying to test Mongoose server method. But when I am testing mongoose web server method, it is giving "failed to open listener" error. 

Below is the complete log:

What could be causing this error. 

Thanks in advance.

Simply that port 8080 is not free on your system.
