After some more faffing with XSP4 and Web.config, I was at least able to
serve a ‘Hello World’ via TCP. So this proves that nginx and mono can
work
together on my setup.
So in going back to the unix sockets, I still have the same problem. As
already suggested, this does look like a permissions issue - which
sounds
solvable.
Having said that, I can’t seem to get past it 
I have chmod ‘777’ (for now) - to no avail.
I ran chmod a+rwx as well - to no avail.
I even tried a different path - sadly, to no avail!
I am sure I am missing something obvious, although I have no idea what
it
could be…
Any advice/help would be hugely appreciated!
Thanks
