Switch from zappar hosting to selfhosting error


hello, im having a problem, i create a web faceAR with unity3d and upload using zappar hosting, it run smooth without error, but when i want to switch to selfhosting(https domain, already registered) i got an error like image i attach

is there something i miss?
im follow the guide and i dont really understand this 2 point

  • Files in the Zappar library ending with the .wasm file extension should be served with the application/wasm mime-type
  • Several files in this library (and likely others in your project too) compress well using Content-Encoding: gzip . In particular you should serve files with the following extensions with gzip content-encoding: .wasm , .js , .zbin , .zpt (when build unity webGL im already select gzip)
    thanks for the help
