Hello everyone! I've been trying to understand why if I have a `Single.concat(getCache(), getRemote())` and I open the app in airplane mode I get straight away `java.net.UnknownHostException` which stops the stream from getting the cached values first.

If I try executing this concat after a pressing a button it will work 100% of the times (getting the cache first and then throwing the exception for the remote one), getRemote is just a `Single` from retrofit
