Giving this a bump, as its rather important.
To be more specific, no traffic ever goes through the topology. As soon as it it started, the error will start.
One time I left it overnight and it connected, but I am unsure how long this took to happen.
And ideas would be great, thanks!

I seems like given enough time (hours), it will eventually resolve and start to work.
I am running storm 0.9.4
