I got the same results when using config V16 and V17. Sometimes I would need to re-boot thye PC 3 or 4 times in order to be able to connect with the miniserver. In the end I found an old back-up, v15.1.8.5, put that in the mini-server and downloaded the equivalent config. I couldn't get hold of config version 15.1.8.20 (which was what I was using before changing to v17).
I have a gen 1 min-server and was wondering if this what was causing the problem when changing to config v17 ??
It is frustrating that I can get a min-server connect with v17 but a a random basis after re-booting my PC. Any thoughts??
