Error Message:
HTTP Response Header “Content-Type” configured incorrectly on the server for file https://static.igpmanager.com/26/Build/Viewer_WebGL.wasm, should be “application/wasm”. Startup time performance will suffer.
Additional comments:
The Unity WebGL race viewer seems to load very slowly because
https://static.igpmanager.com/26/Build/Viewer_WebGL.wasm is served with an incorrect Content-Type.
Browsers then disable WASM streaming compilation and fall back to full download + post-compile, causing the delay. This is clearly CDN/edge-dependent. Routing changes (e.g. via Cloudflare WARP) sometimes avoid the issue.
Please ensure .wasm assets are consistently served as:
Content-Type: application/wasm
This occurs regardless of 2D/3D mode.
