Why there is no thumbnail for my forum under the Discover List?

[Jinpeng_Wang]

My forum is listed under the Discover, but it doesn’t show a thumbnail of my forum home page?

Does anyone know about setting up this thumbnail?

It seems your site is taking a while to load, so perhaps our screenshot process timed out? I’ve manually added a screenshot
