DisallowedHost: Invalid HTTP_HOST header: 'treeherder.vips.scl3.mozilla.com'. You may need to add u'treeherder.vips.scl3.mozilla.com' to ALLOWED_HOSTS.

fubar, has anything changed recently that might have caused this?

[Kendall Libby [:fubar] (he/him)]

my first thought was bug 1208044, but that's not on prod. there might have been zlb work during the TCW, but I *think* that was postponed. Any idea what the client IP is? 

treeherder.mozilla.org is a CNAME for treeherder.vips.scl3.mozilla.com, so perhaps something is being overly helpful with name resolution when sending requests. If we can't fix what's sending the requests, it may be easiest to add it to ALLOWED_HOSTS.
