Why does it delay loading after I package it successfully?

Good morning sir
Why does it delay loading after I package it successfully?

After packaging it into an exe in unity, I run the exe and click on the jump interface to jump to the Cesium interface. Sometimes it will be loaded and sometimes it will not be loaded. Is this a connection problem?
Before I package it, it will occasionally fail to load and I need to click the Refresh Tileset button to load it. So I want to get the Refresh Tileset button through a script and add a button ui to the scene so that I can click the button to refresh the scene after packaging. But I did not find the code for Refresh Tileset in Cesium 3D Tileset. How can I solve this problem?
Thanks

Sometimes it will be loaded and sometimes it will not be loaded. Is this a connection problem?

I’m not sure. Sounds like it could be. What tileset are you using?

But I did not find the code for Refresh Tileset in Cesium 3D Tileset.

It definitely exists, and is accessible from both Blueprints and C++. I’m not sure why you were unable to find it.

It’s the default one in cesium

There is no “default one” in Cesium for Unity. We can’t help you if you don’t provide specifics.

It’s the tile set (Cesium World Terrain) in the official tutorial. What I mean is that after I package and publish unity, run the exe file and click on the cesium scene. Logically speaking, it will load the terrain the same as in unity, but it did not load. Success or slow loading, like this. It stands to reason that the drone is on the terrain, but the terrain is not loading.

Are there any messages in the application log?
