Google Search Console says my pages are blocked by robots.txt or marked noindex. How do I fix it?

This usually means Search Engine Visibility is set to No, which marks every page noindex and makes robots.txt block all crawlers.

1. Go to Settings → Web Settings → General Settings.
2. Under Search Engine Visibility, choose Yes.
3. Click Submit.

Marketing → Get Found on Google shows a red warning while it is off. If it is already Yes, check whether you wrote a custom robots.txt under Settings → SEO Settings → SEO Tools that blocks pages; clear it and Save to go back to the default.

Then ask Google to re-check the pages in Search Console. It can take a few days to clear.
