Have a similar issue, I have site A and B, hosted on the same server, sharing the same IP but have different sub-domain name. Site A is my Discourse forum, Site B is just a site with pages that can get oneboxed.
Since I did a rebuild, I can’t get links from Site B to get oneboxed on Site A, was working fine before, and if I try to paste it here, it works.
Edit: I’ve rebuild back to 1.9.0.beta1 and everything works fine, so definitively something’s weird going on with the latest update, so either my NGINX config don’t play nice with beta2 or domain with the same IP can’t get oneboxed?
Edit 2: I’m not sure what exactly is going on, but I rebuild to latest version, do some tests, everything seems to works fine again, run a “rake posts:rebake” to get the links oneboxed, and now suddenly then don’t want to get oneboxed
Edit 3: Also get a lots of
Failed to rebake (topic_id: 15191, post_id: 95337)

Not sure if related, maybe it’s my server choking or something
