Hi Tony,

Thank you for taking the time to outline the steps you’ve already completed.

Sage Accounts Production is used by a large number of customers to successfully submit to Companies House, and we are not seeing this issue being reported more widely at the moment. Based on the error you’re receiving and the limited information available, this would suggest the problem is likely related to something specific within the local environment rather than the software itself.

Although you’ve already checked a number of key areas, connectivity issues of this nature are most commonly caused by local security, firewall, antivirus, or network restrictions that prevent the application from reaching Sage services, even when internet access appears to be working normally.

To help identify the exact cause, we would recommend contacting your local IT support, or Sage Customer Services, who can work through this with you in more detail and carry out targeted troubleshooting of your setup. They’ll be able to check logs, confirm connectivity requirements, and help determine whether anything on the local machine or network is blocking the connection.

You can contact Sage Customer Services via the usual support channels, and they’ll be happy to assist further.

Andy,
Sage UKI
