Featured Image not uploading Creating Posts through MainWP

I have the perfect use case to distribute posts to multiple child sites using MainWP but when I create posts using either Content Operations > Manage Posts or the Article Uploader (.txt version) I am unable to get the Featured Image to publish to the child site. All other areas (title, body, excerpt, categories, etc.) are all Posting very quickly to the child sites I select and any body area images are successfully added as part of the post. It is only the featured image that does not work.

I use GridPane as my server management tool and spun up a vanilla WP install that only has Classic editor and MainWP child installed on the default theme. I am not seeing any errors in the NGINX error logs or anything being blogged via Cloudflare

Hey @PWS-Scott

Welcome to the MainWP community!

1/
From MainWP > Sites > Content Operations > Manage Posts, can you try reproducing this issue with a small JPG file? This will help us rule out problems related to file type or file size.

2/
Does this happen only with some child sites or with all?
Are they all on the same host?

3/
Can you please post the community system report from your MainWP Dashboard for review? The report is located in your Dashboard under Info → Server (your-mainwp-dashboard.com/wp-admin/admin.php?page=ServerInformation), on the top right of the page.

4/
When you’re creating a post with a featured image, is the post itself created successfully and only the featured image fails, or does the whole post creation fail?

Thanks for the additional info @PWS-Scott.

Nothing here stands out as an obvious issue.

Would you mind opening a private Help Desk ticket so we can collect some additional information & investigate further?

Please refer to this Community thread by its URL in the ticket.

Ok, thanks I have opened a ticket

The issue was caused by the MainWP Dashboard being behind a Cloudflare proxy.

This made it impossible for the child sites to fetch the images from the MainWP Dashboard.
