My ISY-99i is not sync'ing with the NTP server. I noticed it this morning when I checked to see if it had advanced to DST correctly (it didn't). When I hit the Sync Now button, I receive either a Java socket time exception error or a "request failed". The log shows a -60001 R/C. To get around the problem I just sync'ed with my PC.
Now I suspect that this is not happening all the time as the log only shows random errors over the last 30 days, it's just that the one day you really want it to work it didn't. I'm not not sure what the errors are telling me and if I need to do anything. BTW, I also sync'd several PCs manually with a different NTP server without problems to make sure it wasn't something network related. Is this a server issue maybe?
