As from 15 minutes ago I am a bit freaked out. All websites on my VPS are down, the VPS is up and running and I cannot login to WHM because it's down.

I did not even change anything, just suddenly out of the blue. I was browsing through WHM an hour ago with no problems.

Yesterday I installed KernelCare with a regular Kernel of my CentOS 6.9 VPS. That's it.

Has anybody got an idea how to trace this problem?
You could take a look here for clues:
WebHost Manager »Plugins »ConfigServer Security & Firewall > Firewall Deny IPs

Search for your IP in that log, edit it out, save and restart firewall.

While you're there, visit here:
WebHost Manager »Plugins »ConfigServer Security & Firewall > csf.ignore - IP Blocking, Edit lfd ignore file

Add your IP here if you wish.

You could also visit here:
WebHost Manager »Security Center »cPHulk Brute Force Protection, click the Whitelist Management tab at top. When you do a popup comes up on right with your IP showing and a link to "Add to Whitelist" for cPHulk.

Assuming your IP does not change often, those steps will keep you safe from blocks.

BTW, if you get blocked like this, and you have a mobile device, disable wifi on it and you should be able to connect to WebHost Manager that way, different IP of course. Then you could unblock yourself if this happens again to you.

how to trace this problem?
cat /var/log/lfd.log|grep "youriphere"
Then if you do not know CSF well, search the phrase/s grepped out of lfd.log in /etc/csf/readme.txt
Then you can tweak appropriate variable in /etc/csf/csf.conf and restart csf by "csf -r"
