## Overview

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

## Common Symptoms

- Backup agent cannot connect to the management console
- Backups fail to start or complete
- Agent shows as offline in the management console
- Connection timeout errors in agent logs

## 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
