More explicit Error Message when internet connection is lost

[na-rodriguezp]

When using the app there was a moment of time in which I had no internet connection and I tried to fetch data and an error message appeared but I did not notice what was the real problem until I noted my internet was not working well. The message that is shown says "Failed host lookup: 'invoicing.co'".
A posible user experience improvement would be an error that says "Data can not be updated because there is no internet connection". Most of the users which are not developers or technology experts would be benefited.

@hillelcoren I would be interested in contributing to this code. If this is not being solved by your team, can I try?

@danger-ahead sure!
