I read the answers in this question, but they still leave my question open: Does Google cache robots.txt?I didn't find a way in the Google Webmaster Tools to invoke a re-download of my robots.txt.Through some error, my robots.txt was replaced with:User-agent: *Disallow: /And now all my content was removed from Google search results.Obviously, I'm interested in correcting this as soon as possible. I already replaced the robots.txt, but I can't find a way to make Google update the cached version.
Can I invoke Google to check my robots.txt?
google;google search console;robots.txt
You can't make them re-download your robots.txt when you want them to. Google will re-crawl it and use the new data whenever they feel it is appropriate for your site. They tend to crawl it regularly so I wouldn't expect it to take long for your updated file to be found and your pages re-crawled and re-indexed. Keep in mind that it may take some time after the new robots.txt file is found before your pages are re-crawled and even more time for them to reappear in Google's search results.
