Lightroom version 2015.10.1
Mac OS 10.12.2
iMac (Retina 5K, 27-inch, Late 2014
AMD Radeon R9 M290X 2048 MB)
The boxes under Preferences>>Network are both blank. But then, I don't remember ever having anything in those boxes. I am working from home and don't remember ever needing a proxy for Lightroom. I, frankly, don't even know what to put in these boxes for a home network.
I tried the procedure suggested here and it seemed to work after I rebooted:
Right now, I can synch with LR Mobile again. Hopefully, it will keep working. Thanks for your help and quick response so early on a Monday morning.
Sorry that I didn't reply sooner but I've been busy on other things. Right now, the Lightroom is syncing, so I was not able to try your suggestion above. I am working via WiFi and my computer is about 25 feet from the router and has a super strong signal. Everything else seems to be working fine on my WiFi.
If I have troubles again, I'll try your suggestion and reply to the thread.
