May I ask if this behaviour continues even when Cloudflare is in “Pause” mode for your domain? :thinking:

You could determine if this behaviour continues even by using a “Pause” option at Cloudflare as follows:

  1. Use the “Pause Cloudflare on Site” option from the Overview tab for your domain at dash.cloudflare.com .
  2. The link is in the lower right corner of that page.
  3. Give it five minutes to take effect, then make sure site is working as expected with HTTPS.
  4. Re-try with updating.
  5. Upon success, un-pause and continue using Cloudflare.
