Earlier today I stopped the indigo server and shut down the mac mini on which it runs in order to make some changes to the UPS and system power wiring. I did stop the server and quit indigo, and shut down the mac mini appropriately.
After I made my adjustments and brought it back up, I can no longer connect via the client on another mac (on the same network), nor via the web interface, even though Indigo touch on my phone works fine.
The server is running fine. I use the standard ports. I turned off the firewall to see if that would help, but it didn't make a difference.
The only other clues I can offer:
1: the AD2USB Plugin is now malfunctioning as well, even though the AD2Pi is working fine (I connected via its web app, and it is working as it should).
2: Earlier today, before I shut everything down, I installed APC UPS Monitoring program and the associated Indigo plugin. Both were working following install (including when I deliberately unplugged the UPS, though I did have to "update status" to get it to show the evolving data). I did all of that via the second (client) Mac, so I know that up until that point, everything was communicating.
This was the first restart of the Mac after the install of that program.
Any suggestions would be welcomed.
