JPG photo upload fails security checks ??

I took a photo of my arduino hardware with my samsung S7 edge for a discussion thread.

I cropped and resampled it in Photoshop so it was only 194KB

But when I tried to upload the photo I get message that it failed security checks and to consult the administrator. WTF! I’ve been doing same method for years, what’s happened here??

(see attached snippet)

I tried attaching same photo to this post, but same failure. So there’s clearly something the uploader doesn’t like about my photo.

From some devices, you have to use a hosting site like imgur

I have occasionally had problems wth JPGs and then had no problem when I uploaded the same image as a PNG. I wonder if it may be something to do with background (non image) data in the file?
