SiteTag used to have some problems about system performance, and the thumbnails of some websites can not be displayed correctly during the heavy hours. We apologize for the inconvenience.
SiteTag switched to the thumbnail service provided by Thumbalizr, and all the thumbnails can be displayed correctly.
However, since we use the service provided by Thumbalizr, we can no longer update the thumbnails by ourselves but rely on Thumbalizr periodically updates.
