You'd have to make sure your setup is fine to begin with. For what it's worth, I haven't seen anything in 0.17.0.1 that disrupts Armory's connection. You're better off updating regardless.
FYI, If I run Bitcoin Core 0.16.3 instead of Bitcoin 0.17.0.1, Armory 0.96.2 now reports "Connected". So for some reason, 0.16.3 is different from running 0.17.0.1 from Armory's perspective, at least on macOS Mojave.
I've updated the subject of this thread, hoping droark will notice.
Thanks for all your hard work. Been using Armory for years and nothing beats it for securing Bitcoin.
