While it isn't a solution as to why the image proxy isn't working, overall
ShareX is a better alternative to Gyazo/Lightshot. It allows you to upload the images to Imgur automatically, which is almost guaranteed to work with the image proxy.
Thank you.
That's why it was working before and not it doesn't work. Lightshot used to upload images to imgur. Now it doesn't.
That helped. Thank you!!!
