Attempt to set up Backup storage geo-replication between two ACI clusters fails on uploading configuration file to secondary cluster with error message Clusters must be registered at the same account server, e.g.:
Backup Gateways are registered under different account server addresses - one cluster is registered using exact datacenter URL (https://<DC>-cloud.acronis.com), while another cluster is registered under general Cyber Cloud address (https://cloud.acronis.com).
1. Check which address is used on Primary Backup Gateway on Storage Services > Backup Storage > Settings > Certificate tab:
2. Gracefully release Secondary Backup Gateway;
3. Re-create Secondary Backup Gateway using the same address on Acronis account step as on Primary one:
4. Retry attempt to set up Geo-replication between clusters.
Contact Acronis Support if the issue will persist.
