JsonLD: Parsing for some sites is broken, maybe a schema.org change: Loading http://schema.org failed

Code that has been working fine for a few months started breaking today. Any time I feed in a site with JsonLD to get checked for structured data. I get:

Message: Loading http://schema.org failed Code: loading remote context failed

I can visit schema.org just fine with a web browser, so it’s not some sort of block in place.

It is also happening to other people using another library that relies on this one: https://github.com/jkphl/micrometa/issues/34

It’s this section in Processor.php (vendor/ml/json-ld/Processor.php) that’s throwing the error. In the processContext function.

                try {
                    $remoteContext = $this->loadDocument($remoteContext);
                } catch (JsonLdException $e) {
                    throw new JsonLdException(
                        JsonLdException::LOADING_REMOTE_CONTEXT_FAILED,
                        "Loading $remoteContext failed",
                        null,
                        null,
                        $e
                    );
                }
