Symptoms

Backup to cloud fails with error:

Error code: 103                  
Module: 3
LineInfo: 0x8258202786770E01

Message: Failed to resolve hostname baas-fes-us2.acronis.com

Cause

IP addresses in Acronis US and EU data centers have been changed. This change was made to enable redundancy of Internet uplinks.

Solution

You either need to clear DNS records cache or change data center IP addresses in your firewall settings (if your environment has strict firewall policy and you have previously specified IP addresses manually).

To clear DNS records cache:

  1. Open Command Prompt: start -> search -> type "cmd"
  2. In Command Prompt, issue:
    ipconfig /flushdns

To change IP addresses:

  1. In your firewall's settings, navigate to the list of IP addresses allowed through your firewall.
  2. Specify new IP addresses:
