Exchange 2016 with Hybrid Configuration

We have Exchange Server 2016 configured in a hybrid environment. We encountered an error when one of our administrators attempted to install a cumulative update that was the same version as the one already installed. After that, we were unable to access OWA, ECP, or the Exchange Management Shell.
Exchange Server 2016 CU23 (2022H1) 15.1.2507.6

    Hi,
    First, please check the certificate bindings in IIS for the virtual directories, especially OWA and ECP.
