Error NOTICE[23837]: manager.c:3258 authenticate: failed to authenticate as 'admin'

Any clues?

I checked the admin passwords all match. How can I see what IP address the connection is coming from?

Thanks in advanced

Well its coming from your own machine, to get some more info about what particular process is failing to authenticate, start with

tcpdump -nnvvXSs 0 -i lo port 5038

look for Username and Secret in the stream
