Hello there,
I have a backup job which was going seamlessly. but in the last days it was failing after reaching 80% with error message attached below. I tried the job by disabling firewall rules nothing new occurred. All backup infrastructure components are working fine for other VMs. I have also checked firewall logs but there is nothing blocked related to this backup.
Error message:
Error: Unstable connection: unable to transmit data. Failed to upload disk. Skipped arguments: [vddkConnSpec>]; Agent failed to process method {DataTransfer.SyncDisk}. Exception from server: An existing connection was forcibly closed by the remote host Unable to retrieve next block transmission command. Number of already processed blocks: [11956]. Failed to download disk 'VM-Name.vmdk'.
I need to figure out how to resolve this issue immediately.
