Hello Dmitry Parshutin The KSC 11.0.0.1131 was installed and the KES 11.1.1.126 and the Network agent is also latest 11. The problem is KSC database repository task is unable to download Update from Kaspersky Lab and the Screenshot is posted above reply before. As several times and several days it failed, had to use Update Utility tool and tag the update source to it for all KES and it's working. But the main thing that still the Kaspersky Update repository task unable to update KSC repository! As KSC 11.0.0.1131 is installed then where can i find the patch to fix this problem? please Thanks in Advance Deadlock4400

Hello, i have the same issue after installing KSC11. I'm unable to install auopatch A, its not listet and i couldn't find an offline installer.

Kaspersky should update their latest ksc11 to a comfortable version which will be able to bypass those problems sooner.

Same problem here with : - KSC 11.0.0.1131 with autopatch A installed (Up2Date.exe v11.0.0.1188) - KSVLA 5.0.52.677 (so there is no "Traffic Security" module) Task fails randomly.

Found autopatch a at http://dnl-cn2.kaspersky-labs.com/updates/bin/kscp/11.0.0.1131/ installed it but no success. i still get TLS error 54.

Hi guys, i dont know if i understand your problem right, but usually the problem ist, that your ksc download on https and your proxy break the tls (ssl bumping/tls-injection). There are two possibilitys, frist deaktivitact ssl-bumping for the https in the following link. 2nd alternativ change the way ksc download it, not recommanded but often in use, scroll the same link down there are the parameters. https://support.kaspersky.com/15052

Hi, thanks for pointing to a workaround. i'm just wondering why it was no issue in ksc 10? Did it include an invisible fallback to http? btw this command creates the following registry entry: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\KasperskyLab\Components\34\1093\1.0.0.0\Updater DisableKLHttps Value: 1 i guess deleting it and restarting the service will undo the changes.

Hi bitboy, thanks for your answer. Does your problem fix with that?

Yes its downloading now :)

Hello bitboy I agree with you about the "Did it include an invisible fallback to http" The command you show there about registry, if I do the DisableKHttps value to 1 then will the KSC update work? Thanks in Advance Deadlock4400

Hi Deadlock, the command proposed by Patrick Summer https://support.kaspersky.com/15052 klscflag.exe -fset -pv klserver -s Updater -n DisableKLHttps -t d -v 1 creates this registry entry. After that updates were working again but only uses http instead of https.
