No nothing is wrong at your hand it's a general errors that takes place because images from some image hosting sites aren't properly embedded on this forum anymore. Few months ago users were facing such error with Imgur images but now most of the image hosting sites give that error. Only images hosted on talkimg can be embedded without any issues while other images upload on any other host will give some kind of proxy error.

If you really want to view an image in a post but the image is still showing that proxy error then I suggest you to click on quote button of that post and copy the link of the image which you see during quoting and paste it on your browser. You'll be able to see the image directly on your browser.
