I’ve been getting an “Updating Failed” error in WordPress Gutenberg plugin.

Here’s the solution to the “Updating Failed” issue.

  1. Copy your IP Address here.
  2. Log into Cloudflare and click “Firewall”
  3. Scroll down on the “Firewall” page in Cloudflare to the “Access Rules” section.
  4. Paste your IP Address (copied in step #1) into the “Enter an IP, IP Range…” field.
  5. Select “Whitelist” from the dropdown next to that field.
  6. Click the green “Add” button.

All done!

See screengrabs below.
