The case is, I have a MeteorJS app deployed on modulus. When using the Modulus URL e.g. "myapp-12312.onmodulus.net" everything is working fine.
BUT when using a Custom Domain and access the app via "myapp.mydomain.com" (configured in my DNS) I get the following error message:
"Error during WebSocket handshake: Unexpected response code: 400"
Anyone had the same problem with MeteorJS and domains?
kind regards
