Hi,
You can disable the certificate check performed by AltaVault by issuing the following commands:
1. SSH to AltaVault
2. Issue the commands:
enable
configure terminal
no replication ssl verify-certs
3. You may receive a message "failed to connect, no process available" error, but you can ignore this as the setting is saved. After that's done, you can retry the cloud settings wizard. This should succeed.
