Image Upload Fails with "Invalid Response from the Jetpack Site" on vilaandratx.com

[alinclamba]

Summary

A user is unable to upload images using the Jetpack app. They receive the error:

Failed to insert media. Tap to get more information.

Invalid response from the Jetpack site.

Here are two screenshots they shared from the mobile app:

Uploads work fine via WP Admin on a laptop (based on my tests), but waiting for user confirmation.

Details:

• Site: vilaandratx.com (Atomic site with WordPress.com Business plan)
• Jetpack is fully connected (confirmed via Site Health & Jetpack Debug).
• Uploads work fine in WP Admin (tested by me, pending user confirmation).
• Device model: iPhone 13 Pro iOS 18.3.1 (user setup from the logs)
• Jetpack app version: 25.7.1

Findings So Far:

• Uploads via WP Admin (laptop) worked in my tests, but waiting for user confirmation.
• No images appear in the Media Library after the failed uploads.
• The site uses the Classic Editor, but since the Jetpack app doesn’t support it, the Block Editor is used in-app.=
• The user did not see a "Save Draft" option, which suggests the image was never uploaded at all.
• A past GH issue reported similar behavior, though it was closed as stale.

Next Steps & User Confirmation:

We’ve asked the user to confirm:

• If the issue occurs when uploading an image directly to the Media Library in the app (outside of posts/pages).
• If uploads work fine via WP Admin on a laptop (I tested this successfully, but waiting for their confirmation).

Logs provided by the user:

• They are shared in the ticket, not adding them here for privacy reasons.
