Overview

This article addresses issues where the Acronis Agent is blocked by firewall settings, preventing proper communication with the backup infrastructure.

Common Symptoms

Required Firewall Configuration

Outbound Connections

The Acronis Agent requires outbound connections to be allowed through your firewall. Ensure the following are permitted:

• Protocols: TCP/IP, HTTPS

• Ports: 443, 7770-7800, 8443, 44445

• Destinations: Acronis cloud infrastructure and Soteria backup servers

Windows Firewall Configuration

1. Open Windows Defender Firewall with Advanced Security

2. Navigate to Outbound Rules

3. Ensure Acronis services are allowed

4. If blocked, create new rules to allow the Acronis Agent executable

Third-Party Firewall Configuration

If using third-party firewall software (e.g., Norton, McAfee, Kaspersky):

1. Add Acronis Agent executables to the firewall's allowed applications list

2. Allow the required ports for outbound connections

3. Whitelist Acronis and Soteria domains

Verification

After configuring firewall settings:

1. Restart the Acronis Agent service

2. Check the agent status in the management console

3. Run a test backup to verify connectivity
