Thanks for moving the conversation here instead of GitHub, but you haven’t answered all the questions I posted there. As a reminder, they are:

  1. What version of Cesium for Unreal? (you answered this one)
  2. What sort of tileset? Where is it being loaded from? (I think you’re saying it’s from Cesium ion? More detail here would be helpful)
  3. What platform? (you didn’t answer this one at all)
  4. Are there any messages in the log? (you didn’t answer this one either)

1、version：2.10
2、printscreen， from Cesium ion，
3、Windows10
4、It’s worth saying that sometimes you can load successfully, sometimes you can load unsuccessfully, and this is the logs when the load fails。

Based on the log, it looks like your network is simply unreliable. I don’t think we can help you with that; you’re better off contacting your network adminstrator. One thing to note is that Unreal Engine does not use the proxy settings configured in Windows by default. If you need to use a proxy to access the internet, there is a seemingly-undocumented environment variable in Unreal Engine that allows this. See here:
