As part of ongoing system updates, our ssh gateway node host identification keys are changing. Once these keys are changed, you will likely receive a warning that the host key has changed. Please refer to our documentation for more details on ssh host keys and resolving this error (https://docs.icer.msu.edu/Resetting_Known_Hosts/). You can find the most up to date list of ssh host keys in our documentation as well (https://docs.icer.msu.edu/Connect_to_HPCC_System/#current-ssh-host-identification-key-fingerprints).
