• What is the current behavior?

I have an angular application with lazy loaded routes. When I reload page some routes are working fine, but others hang and are pending until timeout, no error is thrown. Is there a way to debug this behaviour? I used this tutorial https://angular.io/guide/universal

@daright I had this problem when using an infinite Observable.interval to do a rotating slider. To fix this, I started only subscribing to the Observable on client side ( using isPlatformBrowser).

You should look out for Observers that get created on init and are never completed.
