@swankjesse Thanks for advice. I don’t have plans for retrofit 2.0 update. All subscribers are configured for error handling. Problem is this exception crashes an app before it could be catched in onError handler.

That’s a problem with your wiring unfortunately. OkHttp throws IOExceptions when the network is unreachable. If you can’t handle that, there isn’t anything OkHttp can do for you.
