The problem is that your config tries to use the /204/204.html 
file, and this will generate 405 error for POSTs, as static files 
doesn't suppport POSTs into them.

(Additionally, trying to use files here doesn't make sense, as 204 
responses doesn't return entities.)

Use something like:

    error_page 502 = /204;

    location = /204 {
        return 204;
    }

instead.
