I’ve been testing some pre-production code via localtunnel to validate the twitter cards before pushing them out for actual validation and out of the blue the validation endpoint has started returning: {“status”:“error”,“url”:"<url i’m testing>",“error”:“Failed to crawl url, debugId: 3557510175088-791063”,“tags”:[],“card_builder_errors”:[]}.
The cards were previously completely valid, I did some some previous throttled messages, so i reduced the testing frequency and now can’t get the URL crawled at all.
