CORS Error #101

I used to authenticate through Authorization header:

HubConnectionBuilder() .withUrl(url, options: HttpConnectionOptions(accessTokenFactory: auth.authorization)) .build()

This works without any problem with version 1.3.9

But when I upgrade to version 1.4.0 the negotiation fails, the browser says "CORS Error"

Enabling logging I get this error:
Failed to start the transport 'HttpTransportType.WebSockets': Unsupported operation: Platform._version
