Hey there Greg! Sorry for the trouble here.
According to our crawl error guide, a 902 means "The crawler resolved an IP address from the host name but failed to connect at port 80 for that address. This error may occur when a site blocks Moz's IP address ranges."
You'll want to make sure you're not blocking AWS, and that your pages aren't larger than 2MB. If you're still having trouble figuring out what's happening, feel free to write into help@moz.com with the actual URL of your site. Thanks!
