Looks like you might be running the app twice (or have another application running on those ports), The GUI wont start currently, see #1165

Thanks. I'm not really running in twice. The log snippet i grabbed is just showing the ports being taken as the webserver did start successfully earlier in the trace, but is continuously attempting to restart to load the GUI which is the erroring portion.

I was able to revert from 2.8.1 down to 2.7.8 and it's working properly now to generate the Tray/Web link
