Alright, so found the answer.
Thanks to msayago for his answer in here
So, I guess my installation came with Remote Mysql by default and I shouldn’t have that. So, after trying couple of things, the resolution was to start a new server, simple Ubuntu, and install Cyberpanel from CLI.
While installing it’ll ask if you want to install Remote Mysql, type no, and that’s it. It’ll work!
Thanks
