Resolve a Sage connection failure

This article only applies to customers connected to Sage 50 (UK), Sage 50 (US) or Sage 200. You also need to be a Compleat Administrator or Company Administrator to carry out these steps.

One of the most common reasons a Sage connection failure occurs is due to changes in the firewall settings on your PC.

There are a number of ports that should be fully open in your firewall settings in order for Compleat & Sage to connect. We recommend asking an IT Administrator in your company to help you check that you have the following outbound ports open:

• 5671
• 5672
• 9350
• 9351
• 9352
• 9353
• 9354
• 443
• 90

If this doesn't resolve your connection failure, please contact our support team & they will look into the connection problem as soon as possible.
