error under staging during image upload – debug code: wpstg-EhUI8NK5-8210

I have successfully setup the staging platform, and want to test different images in a slider. When attempting to upload to the media library, the following error occurs:
The server cannot process the image. This can happen if the server is busy or does not have enough resources to complete the task. Uploading a smaller image may help. Suggested maximum size is 2560 pixels.

I can upload the image to the production environment, (it is under 100kb) without a problem.

I don’t find anything in settings that would address this.

Debug code is wpstg-EhUI8NK5-8210
