As reported in https://meta.trac.wordpress.org/ticket/1860 W.org is responding incorrectly for certain requests, I’m unsure what the cause is and whether it’s a nginx config or not.
Here’s a cURL command to reproduce:
$ curl -v 'https://wordpress.org/plugins/search.php?page=2&q=plugin' * Trying 66.155.40.250... * Connected to wordpress.org (127.0.0.1) port 443 (#0) * TLS 1.2 connection using TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 * Server certificate: *.wordpress.org * Server certificate: Go Daddy Secure Certificate Authority - G2 * Server certificate: Go Daddy Root Certificate Authority - G2 > GET /plugins/search.php?page=2&q=plugin HTTP/1.1 > Host: wordpress.org > User-Agent: curl/7.43.0 > Accept: */* > * Empty reply from server * Connection #0 to host wordpress.org left intact curl: (52) Empty reply from server

They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party directory will hopefully retire soon and this isn’t reproducible against the new directory, most likely due to the change from query variables to rewrites. If this is a wontfix I don’t think anyone will mind.
