I run Norton Online Backup nightly and have all of a sudden started getting A2816 (firewall) errors. I'm using Norton Internet Security for my firewall. Has something changed there? Is there a setting I need to change? I haven't changed anything myself but since all this stuff is on auto-update, who knows what has been changed by Norton.
Solved! Go to Solution.

As the errors seems to be firewall related, you can try to restore the original firewall's settings.
You can also maybe try to set up a rule in order to allow NOBU every connection.
I hope it can help

It would help if I actually knew how to do those things. I have never made any firewall changes so why would it all of a sudden start blocking NOBU?
I was checking my versions of the software and discovered I didn't have the most recent Norton Internet Security after all (so much for auto-update). I've now updated to Norton Internet Security 2012 but it hasn't helped (fixed some minor glitches with Identity Safe but no impact on this problem).
Here are the versions I'm running:
Norton Internet Security 2012 18.104.22.168
Norton Online Backup - current version (can't find out what it is but when I do a version check it says it's current)
Windows Vista Home Premium
I don't know what to do with Norton Internet Security to tell it to allow NOBU. When I go to configure the Smart Firewall, it wants me to identify an executable program to allow. What program do I have to set up? Has something changed with either NOBU or Norton Internet Security that this needs to be done now when it didn't before?

you are right, NIS shouldn't block this connection in general.
From nobu.backup.com/help you can see that the error is only firewall related.
Your computer firewall blocks the backup software from connecting.
This error message is typically a software-based firewall error message. Check your computer's firewall settings. Change the settings to allow online backup run.
Try to ping the following address: symr2a.backup.com
If the ping is successful, the problem might be caused by a firewall or proxy that exists between the NOBU client and the server. Check if the firewall or proxy is set to block SSL (port 443) traffic.
[settings -> network -> smart firewall -> configure in advanced settings -> configure on general rules to see which rules are currently in use].
About the client's exe file, it should be C:\Program Files\Symantec\Norton Online Backup\NOBuClient.exe, but i cannot tell you if there are other processe involved [there should be also a NOBuAgent.exe in the same folder]

Pings are working fine. I can't find any blocking of SSL in either Norton's firewall or my router. I've added NObuClient to my Norton firewall settings. We'll see how things go over night and work from there.

Still same problem. I will try a re-install over the weekend. Hoping somebody from Symantec will join this thread and maybe have some ideas or let me know how I can contact them (other than through the pay-per-hour service).

NOBU client re-install has created a new problem (described in a different thread) but basically, it now thinks I have a new computer and won't be able to run a full-backup because I'll run out of space.
Back to the firewall, I'm going to try a small backup on this "new" computer and see if it works. I've also re-booted my router and wireless radio (it's a radio-signal wireless high speed system).
I have noticed that my internet connectivity is a bit spotty right now (I occasionally have to re-display a page). I had one online chat session affected by that that reported it as a potential firewall or connectivity problem. Is it possible that it's actually just the internet access getting dropped and NOBU is mis-interpreting it as a firewall problem? Would be nice to get the proper error message so I could search in the right area (talk to my ISP) rather than spend days looking at firewalls.

tried a small backup (about 1 mb) and it ran for a while. Last time I checked it was about 87%. Now I check to see if it's done and it's got the same A2816 error. If there's a firewall problem, how can it get so far before realizing it. This must be something else.
