> Hi, I’ve managed setup a discourse instance with discourse\_docker, with version 2.7.0.beta4. I’m facing a curious problem that with the same url it did generated onebox preview, however it fails several days later. the url in problem is [Dapr可视化指南-InfoQ](https://www.infoq.cn/article/pckmUYf2mpc3Erg74hSU) The error prints as below. [20210309141516] But I can find “og:description” and “og:image” in this url meta tags. I’m not familiar with discourse code, any help will be appreciated, thanks!
