Connection over network is blocked by network throttling rules

To resolve this issue, you will need to identify which network restrictions are in place and then either disable the restriction or change the state of the machine so that the backup is not interrupted by the restriction.

• For Veeam Agent Backup jobs operated by Veeam Backup & Replication the network restriction settings are within the Protection Group settings.

• For Veeam Agent for Microsoft Windows standalone deployments, the network restiction settings are in the Settings menu under "Manage Networks."

Case Example

The most common issue seen by Veeam Support occurs when the remote machine's network connection has been marked as a metered connection and causes the "Restrict metered connections usage" rule (which is enabled by default) to prevent the job from running. In such a situation, a decision must be made to either:

• remove the metered connection state from the NIC.
  
  or
• disable the restriction rule within Veeam.
