Summary

This guide helps you with this error message when opening Sage 50cloud Accounts.

Description

When opening Sage 50cloud Accounts, one of the following messages may appear:

  • 'Unable to connect to Sage Data Service on machine [computer name]'
  • 'Data service unavailable on this machine'

This occurs if the Sage Accounts Data Service is the wrong version or stops running on the computer that stores your Sage 50cloud Accounts data. If Sage 50cloud Accounts was working previously, you can normally resolve this in a few easy steps by restarting the Sage Accounts Data Service. Let's take a look.
