yes, it is not yet reviewed/merged I guess. In any case, it just improves
error reporting
and doesn't change any functionality.

all good here

also looks good

So what happens here is that
* bankd connects to server (via 127.0.0.1)
* server stores that bankd is at 127.0.0.1
* client connects to server (192.168.70.241:9998)
* server tells client to use bankd @ 127.0.0.1
* client tries to connect to bankd @ 127.0.0.1, which fails, as it is not on
localhost
So the problem in your setup is mixing loopback addresses with routed network
addresses.
In case of doubt, start with running bankd + server on separate machines, and
see if that works. If it does, try to migrate the working configuration to
something where multiple components run on the same machine, but without using
non-routable IP addresses.
