The most common cause for this error is slow internet network download speeds. This problem can happen when a proxy or firewall holds the content that LiveUpdate requested for longer than LiveUpdate's default time-out value. Because some networks scan files at the perimeter, Symantec added a configurable time-out value to LiveUpdate version 2.5. To learn how to configure the time-out value of LiveUpdate 2.5, read the following document:
This error message appears if LiveUpdate does not have the correct rights and permissions to pass through the firewall. On Windows 2003/XP/2000/NT, LiveUpdate requires administrator-level rights.
Presence of a legacy file:
The presence of the legacy file S32LUHL1.DLL can cause this problem. Look for the S32LUHL1.DLLfile in the following folders and then rename the file, if found:
- Program Files\Symantec\LiveUpdate
- Program Files\SAV
- LiveUpdate needs access to the following TCP ports:
- Port 21 (FTP)
- Port 80 (HTTP)
- Port 443 (HTTPS)
- Disable setting "Deferred scanning for files larger than 2MG" in the FTP area of Firewall.
This problem can happen when the files that LiveUpdate uses become damaged. Delete the contents of the Downloads folder, and then run LiveUpdate again.
Make sure the hidden files are shown
- In windows Explorer click on tools
- Folder option and click on view tab
- Click on the radio button to show hidden files
- Also uncheck the option to "Hide protected Operating system files"
- Click on apply and click Ok
Navigate to :-
- C:\Program Data\Symantec\LiveUpdate\Downloads
Delete the contents of Downloads folder
Old files in the cache:
LiveUpdate may freeze after downloading 3500 KB within Backup Exec 2010 R2 and Error "LU1835: Connection to the LiveUpdate server failed" pops up.
1. From Control Panel, change LiveUpdate Configuration HTTP settings to "I want to customize my HTTP settings for LiveUpdate". Enter proxy IP and port number.
2. Change the Update Cache size to 30MB and click "remove all files from cache".
3. Run LiveUpdate from Backup Exec again.
Live Update Corrupted:
This problem can happen when LiveUpdate itself becomes corrupted.
