Hi All!
The problem of not accessing the KSC Web Console is has solved.
I have uninstalled KSC Web Console using the tool https://support.kaspersky.com/ksc13/tools/15021
And reinstall new KSC Web Console and add the valid certificate to the KSC Administrator Server.
Make sure the certificate KSC server in "For Windows—%ALLUSERSPROFILE%\Application Data\KasperskyLab\adminkit\1093\cert" is a valid certificate.
