Unknown Error uploading images

Hello. 

I have had 2 different sites show "Unknown Error" when trying to upload images from my graphic artist into CMSB.

I simply resaved the images from Photoshop file> Export as to new JPGs and they uploaded fine.

The only difference I see is a large amount of meta data in the file from my graphic artist. I'm not sure yet if he used a different process (haven't seen this issue from him before and just emailed to ask) or if he used different software or something. I'm also not sure if he had sRGB toggled or if that may be an issue in CMSB.

Attached are the settings I used that work. However, I am not sure if this was the issue. 

Please advise or let me know if you would like the example files to investigate (prefer to email).

Thank you!
