DAHUA XVR Email Motion pictures COULDN load

Hi guys, i have a problem with the dahua xvr motion email photos.

I have configured to IVS to send email notification with a photo attached to . But the thing is that the email is coming but the picture atacched is broken. Says COULDN load. ( screenshot below )

Does anyone have any clue why this is happening.

I have another XVR at another bussined , and it works just fine.
