[HELP] - Cobalt Strike's C2

[qGodless]

I moved from Metasploit to cobalt strike due to not having the ability to keep my pc UP for connections, I bought a low end VPS with these specs:

My problem is When connecting to the C2. It refuses to, [Connection refused]

Note:
I can do nmap scan only with -Pn
The port on 50050 is open
I tried different CS versions
This is the jar version

openjdk version "1.8.0_292" OpenJDK Runtime Environment (build 1.8.0_292-8u292-b10-0ubuntu1~14.04-b10) OpenJDK 64-Bit Server VM (build 25.292-b10, mixed mode)

Also, make sure you have the right port set in teamserver script.
