Overview

The Acronis Cloud Connection Verification Tool is used to test connectivity between a device and the Acronis Cloud data centre. It helps diagnose network-related issues that may prevent backups, agent registration, or cloud storage access.

This tool is typically used during troubleshooting when:

  • Backups to Acronis Cloud fail

  • Agents cannot register to the cloud

  • Connectivity or firewall issues are suspected

Applies to

  • Acronis Cyber Protect Cloud

  • Acronis Backup Cloud / Acronis Cyber Cloud

  • Devices backing up to Acronis-hosted cloud storage

What the Tool Checks

The tool verifies:

  • Network connectivity to Acronis Cloud endpoints

  • Required ports (typically HTTPS / TCP 443)

  • DNS resolution

  • Access to specific Acronis data centre URLs

It helps identify whether a firewall, proxy, DNS, or ISP restriction is blocking communication.

How to Use the Tool

  1. Download the Cloud Connection Verification Tool from the vendor article.

  2. Run the executable on the affected machine (no installation required).

  3. Select the appropriate Acronis data centre (if prompted).

  4. Start the test.

  5. Review the results for:

    • Failed endpoints

    • Port connectivity issues

    • DNS resolution errors

The tool generates a report that can be shared with support if required.

Interpreting Results

  • All checks successful - Connectivity to Acronis Cloud is working correctly.

  • Failed connection checks - Typically indicates:

    • Firewall blocking outbound HTTPS (TCP 443)

    • Proxy misconfiguration

    • DNS issues

    • Deep packet inspection interfering with traffic

If failures are detected:

  • Confirm outbound TCP 443 is allowed

  • Whitelist required Acronis URLs and IP ranges

  • Bypass SSL inspection where applicable

  • Ensure proxy authentication is not blocking the agent

Impact

If connectivity to Acronis Cloud is blocked:

  • Backups to cloud storage will fail

  • Agents may show as offline

  • Recovery operations may not complete

Resolving network restrictions is required for normal operation.

Action Required

  • Run the Cloud Connection Verification Tool on affected endpoints.

  • Review results and remediate any blocked endpoints or ports.

  • Re-run backup or registration after resolving connectivity issues.

  • Escalate with the generated report if further support is needed.

Additional Information

This tool is intended for connectivity diagnostics only. It does not modify system settings or firewall rules.

For persistent issues, review:

  • Local firewall configuration

  • Network perimeter firewall rules

  • Proxy configuration

  • SSL inspection policies
