How to use system certificates?

[pikondrej]

I have the server side running and use basically self-signed certificate. I have the certificate properly installed in the system. Could you please tell me what can I do to make CodeChecker use the system certificates / or / use specific certificate / or / disable SSL verification?
Thank you

EDIT:
I wasn't clear. The server side is running fine. I am having trouble connecting from another machine using the CodeChecker as client. The login cmd ends up with:
certificate verify failed: unable to get local issuer certificate
The cert should be properly installed on the client side system (docker Ubuntu 20.04).
The connection works when specifying the system certificates or via wget/curl:

import http.client;
import ssl;

context = ssl.SSLContext(ssl.PROTOCOL_TLS);
context.load_verify_locations(cafile='/etc/ssl/certs/ca-certificates.crt', capath=None, cadata=None);
connection = http.client.HTTPSConnection('codechecker.x.com:443', context=context);

connection.request('GET', '/');
response = connection.getresponse();
print(response.status);

I tried all I could find to disable ssl check or set up correct path. certifi.where() returns the /etc/ssl/certs/ca-certificates.crt. I tried exporting CURL_CA_BUNDLE, REQUESTS_CA_BUNDLE and SSL_CERT_FILE, but nothing works. I am unfamiliar with python, so I don't know what is its behavior when it comes to certificates and I can't recognize if CodeChecker is doing something "different" perhaps.

The easy answer would be to either copy or symlink the cert.pem and key.pem into the server's config-directory, where CodeChecker searches for it.
Symbolic links would allow the system-wide certificate to be updated without having to do the copy again.
