Ok, I figured it out eventually. While I did the initial setup " https://docs.hak5.org/cloud-c2/guides/enabling-cloud-c-as-a-service-on-boot-and-exfiltration" from this link I was had to change the service file because of a typo, after I was already finished with the whole setup. The service status was running with errors. I fixed it and the service status appeared online and did not show any errors, but I could not connect to the web api. The solution to this was to redo the last sequence of restarting daemons and enabling,starting cloudc2.service with systemctl commands. Now it works smoothly so I hope if anyone has the same issue this could help. :)
