Why doesn't 3proxy work on VDS CentOS 7?

Question

linux

Good evening comrades. I've searched all over the Internet, tried many configurations, but nothing works.
The bottom line is, I decided to try to raise a proxy on a weak VDS server. Because on the Internet, the installation of 3proxy was described in some detail, I decided to stop there. Initially, everything went according to plan and everything seemed to work out, but when it came to launch, a bunch of errors began to pop up, I defeated some of them and it seems like 3proxy even started, but I can’t connect to it.
Now more about the problem:
I can't connect to the proxy
What we have: CentOS 7
Here is a screenshot of the settings in the 3proxy.cfg file

Here is a screenshot of the logs:

When executing the command: netstat -an | grep -i listen
it says that port 4239 and 4555 - Listen
Added 2 lines with required ports to ip-tables-config file:

iptables -A INPUT -p tcp -m conntrack --ctstate NEW -m multiport --dports 4239 -j ACCEPT
iptables -A INPUT -p tcp -m conntrack --ctstate NEW -m multiport --dports 4555 -j ACCEPT

It seems like everything that could be added, if anything else is needed, ask. Of course, I clumsily changed the IP addresses, but I changed them :)
P.s. if you try to connect to the proxy with this configuration, (111.111.111.111:4239 or 4555) then nothing happens, it does not even ask for a login password.
I ask you not to be very indignant, I'm not a pro in this matter, but I'm just starting to get interested.
Thank you all for your help.
