since we changed the license key file we've got the problem that our antivirus software on client side doesn't update via core server.
If we try to update manually the antivirus client jumps to 95% and download file of 5,7 KB. After that the software says that the virus definitions are out of date again.
Antivirus settings are correct and was not changed before and after license update. Proxy settings are correct, too.
Update via Kaspersky server seems not to work properly, too. The tool loads about 3 MB and changes the status to successfully. About 10 minutes later the status changes to "out of date" and the
old virus definitions are displayed.
Do you have any idea?
