So I fired up a Raspberry Pi 3 and… ….I still couldn’t connect with the servers.
But I could do all the usual office-type tasks at full speed and with out any inconvenience.
Web-browsing was slightly slow, maybe because the little machine is not caching so much?
Anyway, it was so convenient, I just kept on using for the rest of the day.
And when the mysterious veil was lifted from the servers, it connected perfectly well to them too.
Well done Raspberry Pi.
BTW, I have treated it to the official enclosure, as all those bare short-able connections offended the residual engineer in me.
