Hello!

First post here so I hope you can help! I'm not much of an expert by a long stretch but I'll do what I can!

We deploy a Mapnik server using the opentileserver.sh script - found in the below link.
https://github.com/MapFig/opentilese...ntileserver.sh

This works great, however we now need to update the maptiles as they are getting out of date. So, running the script designed to update the tiles results in just a sea of red 'failed to load' type tiles when you browse the page. Can anyone suggest why this maybe failing? The script seems to complete without error, it's only when the page is browsed that we see the issue.

Thanks
