Last phabricator in date
Nginx

I was writing a text and then I embeded an image :

It's just a test like you can see in this screenshot {F64}

Instead of seeing the embded image, It internally failed (500). So I investigate more and look nginx logs and chrome debug (at the http header for the contents thats fails).

So I get something like this (for mozillia and same for chrome:

Naturally I browse https://a.a.info/file/xform/preview-220/PHID-FILE-l5mbhxdxotbybwwtbqef/gmzq5erwnn4fnlscgpgf/. And then get this exception.

Note that this is the case only for embeding image so meme or normal file or even sound work like a charm.
