XML-RPC methods are missing

  • I’ve just setup a new WordPress site on an AWS instance, and the basics seem to be working, however I’m unable to connect to it from the WordPress Android app.

    If I give my site address, as either https://www.notasnark.com, or https://www.notasnark.com/, then I get the following error:

    Couldn’t connect. Required XML-RPC methods are missing on the server.

    I first tried this after a basic install with only the Coldbox theme added. Installation process was:

    1) apt install wordpress (to get all the dependencies)
    2) Install SSL certs using let’s encrypt (HTTP redirecting to HTTPS)
    3) download latest wordpress.tgz from the wordpress site, and setup site using that.
    4) Checked that both HTTP and HTTPS available from everywhere.

    I’ve since tried adding the Manage XML-RPC plugin to see if that gave any details on what was enabled or not, but couldn’t see anything useful. The plugin is now deactivated.

    Some digging around hinted at trying the following:

    $ curl https://www.notasnark.com/xmlrpc.php
    XML-RPC server accepts POST requests only.

    So I can reach the endpoint. Looking at my Apache logs when the Android application is trying to connect, I get the following:

    This is my first attempt at using WordPress, so I don’t have much experience. Any ideas about what I may have done wrong greatly appreciated.

    Thanks,
    Sam.

  • I don’t see any signs of WordPress being installed at this server.

    In between my post and your reply, it was moved to blog.notasnark.com. I’m now also using the disable XML/RPC plugin to completely disable the feature since I couldn’t get it to work.

    So I’m trying to take a look at this again. I’ve disabled the XML-RPC plugin, and I still get the same error as before on the new site (which is the old installation, just with a different hostname).

    The new hostname is https://blog.notasnark.com/

    When I try to connect using the Android app to blog.notasnark.com, I get the following in my Apache logs:

    
"POST /xmlrpc.php HTTP/1.1" 200 589 "-"
"POST /xmlrpc.php HTTP/1.1" 301 603 "-"
"GET /xmlrpc.php HTTP/1.1" 405 444 "-"
"POST / HTTP/1.1" 200 9172 "-"
"POST / HTTP/1.1" 301 582 "-"
"GET / HTTP/1.1" 200 9173 "-"
"GET / HTTP/1.1" 200 9172 "-"
"GET /xmlrpc.php?rsd HTTP/1.1" 200 576 "-"
"POST /xmlrpc.php HTTP/1.1" 200 441 "-"

    I’ve paired down the output to make it more readable, but in each case the user agent is:

    “Mozilla/5.0 (Linux; Android 9; Pixel 2 XL Build/PQ3A.190801.002; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/76.0.3809.89 Mobile Safari/537.36 wp-android/12.9”

    If I take a look at /xmlrpc.php?rsd in the browser, then it exists and returns some XML:
