Angular Ivy has changed the way server.ts performs bootstrapping. Basically, you have to run

ng add @nguniversal/express-engine

And then adjust your old SSR-related code in main.server.ts, server.ts/main.ts, tsconfig.server.json, app.server.module.ts towards the newly generated server.ts. Most probably the created server.ts will be placed in a different path, therefore don't forget to change the main path for server in angular.json.
