From the log it seems that the server has correctly started up. Can you describe what error you are seing?
Also can you try to open http://[::1]:34451/version in a browser?

[TolganLight]

The error was: connect ECONNREFUSED ::1:32829

I can confirm that I am no longer getting this error after a second machine reboot. Seems this error is intermittent. Happy for this to be closed.
