An Inconvenience But Could be an Issue

[NewTech]

I really hate to be such a pain but...

 

Lately it seems that I need to log into my ISY at least two or three times before I am able to log into a fully functional Administrative Console. I am not always able to "get" the device levels in the network (they remain blank). And, sometimes even after I log in several times I don't get ALL levels in the main menu screen when I click the network folder.

 

I also tried to upgrade to 2.7.9 but I am once again having the same issues I had when trying to upgrade to 2.7.8. Here is a link to that post: http://forum.universal-devices.com/viewtopic.php?t=3719

 

The more I think about this the more I think I do have a problem with the ISY that really needs to be looked into. There really shouldn't be a reason why I always seem to have so much trouble upgrading.

Same thing happens to me when I log in. I then close my browser, clear java cache and i am usually able to get in. i agree... it shoudn't be such a process to simply log in.

 

by the way, i also had trouble upgrading today but i seem to be experiancing a different hang up in the install process.

Hi to both,

 

There are two issues at hand here:

1. Firewall ... please let me know what firewall software you have so that I can look into it

2. Java cache ... if your system is still using the old client, you will have many unexplained behavior. As such, please ensure that you have cleared your Java cache

 

With kind regards,

Michel

Hi, Michel!

 

To answer your questions:

 

1) My firewall is Trend Micro. In the past I've not had issues with the firewall BUT our subscription was scheduled to end on Feb. 11, 2010 so I did just renew it which forced me to download an updated version. I believe now I have Trend set correctly to allow the ISY through because all appears to be okay for now.

 

2) This where I wouldn't care if you called me stupid because that's just how I feel! Apparently I wasn't thinking because I was trying to clear the Java cache WITHOUT closing all open browser windows. Duh!!!

 

So, for now, I think everything is okay. Thanks once again for your dedicated service to my ISY issues.

Still might have an issue with Java. Here is what I get when Java does not load:

I've cleared the Java cache and even gone as far as to reinstall Java but nothing seems to work.

 

Any ideas?

Hello again,

 

Yes, this does make sense. It means that the client code was not found. Would you be kind enough to let me know which URL you use? Is it possible that that your upgrade never completed?

 

With kind regards,

Michel

Michel, not sure I know what you mean by the URL I use but I log into my ISY via http://192.168.xxx.xxx/admin which I have saved as a favorite.

 

And, yes, it is VERY possible that my upgrade to 2.7.8 did not load completely considering I now am not able to upgrade to 2.7.9. I constantly get error messages that say the connection was forcibly closed by the remote host and this one: upgrade failed :java.lang.NullPointerException.
