Check ports in Windows or Linux 

You can check if the ports and hostnames are open by using Acronis Cloud Connection Verification Tool.

Alternatively, you can check if the ports and hostnames are open in your network by issuing the telnet command. If they are accessible, you will see a blank screen after issuing the command:

telnet rpc.acronis.com 443

If they are not accessible, you will see a respective failure message:

In Windows Vista and Windows 7 you may need to enable telnet first:

  • Go to Start -> Control Panel -> Programs;
  • Under Programs and features, click Turn Windows features on or off;
  • Check both the Telnet Client and Telnet Server boxes;
  • Click OK.

Open ports in Windows Firewall and allow Acronis software through firewall:

See Acronis Software: Allowing Acronis Products Through Firewalls

Check ports on Mac

  1. Open Network Utility.
  2. Click Port Scan.
  3. Check hostnames and ports of your datacenter (see this article).
    E.g. you are backing up to Strasbourg, then you should check these ports:
    cloud-rs-eu1.acronis.com 55556
    cloud-fes-eu1.acronis.com 44445
    web-api-tih.acronis.com 443
  4. Check the output:

Allow Acronis software through Mac Firewall:

  1. Click Apple, then System Preferences, then Security & Privacy. Click Firewall.
  2. Click the Lock icon and type in your administrator user name and password. This will let you make changes to your firewall settings.
  3. Under Firewall Options then click the "+" button to add Acronis software to the list. Click OK.
