Having a very similar problem as wideglidejrp. My desktop HD crashed and I just replaced it yesterday and did a clean install of OS 10.9.5. I am currently rebuilding that hard drive with a Time Machine backup. However, that desktop is NOT running my Indigo 6 app. I have a Mac Mini running Indigo 24/7. After the desktop HD replacement, Indigo Touch on both my iPad and iPhone began displaying "Failed to connect: The Request Timed Out." When I attempt to tap the dialog box under "Choose an Indigo Server" nothing happens –the app is frozen. I force quit the app (double-tap the home button, then swipe up) but that doesn't allow the app to function properly. I've restarted all my machines (Mac Mini, iPad,iPhone) attempting to clear their respective "minds", but nothing appears to help.
I've followed the suggested workarounds–uninstalled Indigo Touch (several times)–but I get the same issue. Indigo Touch "sees" my Indigo Server but will not connect. Also, I cannot connect via Safari on my desktop. It also times out after several minutes.
The odd thing was everything was working fine until I had to swap out a dead hard drive from my desktop . Any ideas?
