That _always_ happens: the quickest way to find something out is to post
to say it's not working and find the fix immediately yourself. Unplugged
/intermittent network cable is always a good one for that.
Likewise, everybody else can see an error in a configuration file in 15
seconds that you've been agonising over for 24 hours.
That's one of the good reasons to be able to share and not feel bad about it
and this list is normally not judgmental - we've all been there at some time.
Welcome to the club of facepalm people - really glad it's now working for you :)
All best, as ever,
