host = "influx.ntw.xxx.yyy"
database_name = "test/5m"
token = "my_api_key"
table = "test"

client = InfluxDBClient3(host=host,

                        token=token,
                        verify_ssl=False,

result = client.query("SELECT * from test")

print(result)

Additional info

So I tried ssl False, enforce context or all other options and still getting the err

`python
from influxdb_client_3 import InfluxDBClient3
import ssl

cert_path = "influx.ntw.xxx.yy.pem"
ssl_context = ssl.create_default_context(cafile=cert_path)

host = "influx.ntw..xxx.yy"
database_name = "test_petr/5m"
token = "token"
table = "test"

client = InfluxDBClient3(host=host,
database=database_name,
token=token,
# verify_ssl=False,
ssl_context=ssl_context
)

result = client.query("SELECT * from test")

print(result)
`

the same err:

checking ssl handshake works
`
import ssl
import socket

def evaluate_ssl_handshake(host, port=443):
try:
# Create a custom SSL context with your CA bundle
context = ssl.create_default_context(cafile="influx.ntw.xxx.yy.pem")

    # Set up the socket with an SSL context
    with socket.create_connection((host, port)) as sock:
        with context.wrap_socket(sock, server_hostname=host) as ssl_sock:
            # Print SSL/TLS certificate details
            cert = ssl_sock.getpeercert()
            print(f"SSL handshake to {host} successful!")
            print("Certificate details:")
            for key, value in cert.items():
                print(f"{key}: {value}")
            print(f"TLS version: {ssl_sock.version()}")
            print(f"Cipher suite: {ssl_sock.cipher()}")
except ssl.SSLError as e:
    print(f"SSL handshake failed: {e}")
except Exception as e:
    print(f"An error occurred: {e}")

Specify the host and port

host = "influx.ntw..xxx.yy"
evaluate_ssl_handshake(host)
`
this results
python stash/shake2.py
SSL handshake to influx.ntw.xxx.yy successful!
