Nginx directive inheritance is (in general) "by replacement" or "not
at all".

If you have a directive in a location, that is the full set of
that-directives that applies to the matching request.

Since you have an error_page at server{} level, any error_page defined
at http level is irrelevant for any request handled in this server{}.

http://nginx.org/r/error_page

If you want a distinct set of error_page directives to apply at
server{}-level, you must write them all there (perhaps by "include"ing
a file).
