going through a proxy and disabling host verification is not effective

[joseluu]

Bug description

Disabling host verification on an https connection fails

Context:

Proxies doing packet inspection do their own ssl handshake with the target host and with the user machine. As a consequence, the user machine sees the proxy certificate rather than the target host certificate. For this reason it is convenient to disable the host verification on the user machine.

how to reproduce

prerequisite: use https connection going through a proxy doing packet inspection

   service = QiskitRuntimeService(
        channel='ibm_quantum_platform',
        token=token,
        proxies=proxies,
        verify=False,  # Set to False if you have certificate issues
        instance='Instance_2026'
    )

Expected behavior

Connection happens without error

environment of execution

• SDK Version 0.73.2
• Python Version 3.11
• Name of service used: QiskitRuntimeService
