Facebook OpenGraph 图片不被接受
Facebook OpenGraph image not accepted
我已经在我的网站上定义了一个 OpenGraph 图像（url：https://www.psychotherapiepraxis.at/pt-forum/），但是 Facebook 对象调试器告诉我
og:image was not defined, could not be downloaded or was not big
enough. Please define a chosen image using the og:image metatag, and
use an image that's at least 200x200px and is accessible from Facebook
由于图像是500x500px，我很奇怪为什么它不起作用？如果直接在浏览器中输入 URL，该图像也应该可供 Bots 访问，并且可以正常显示。关于为什么它不被接受的任何线索？
我在调试器中刷新了数据，错误信息没有了，但是还是：
Use images that are at least 1200 x 630 pixels for the best display on high resolution devices. At the minimum, you should use images that are 600 x 315 pixels to display link page posts with larger images.
...
Try to keep your images as close to 1.91:1 aspect ratio as possible to display the full image in News Feed without any cropping.
