[Failed to establish the HTTPS connection: TLS error (54)]

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.

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.
