Can't able to view the image(Icon avatar) in Email Notification from nextcloud

Hello, I am experiencing a 403 error when trying to view the avatar in my Email notification. Despite trying various techniques, I have been unable to resolve this issue. Would anyone be able to assist me in resolving this problem? Thank you.
