There seems to be a problem with coinos (or our communication with it) where if it can't send the payment, it just doesn't respond. We have plans to work around this, because we shouldn't rely on best-case wallet implementations, but that's the underlying cause.

@adam_coinos_io what's the recommended way for SN to determine if a coinos account can't send a payment? Do you report an error back and we're missing it?
