Hi Bryn_S,
The connection error message you are encountering is a known issue that can be related to several factors, including network connectivity, software configuration, or server-related problems. To address this, ensure there are no firewall or security settings blocking the connection to the MYOB servers, as you have already tried different locations and internet connections. Verify that your MYOB software is up to date, as updates often include fixes for known issues.
Additionally, check if there are any ongoing server issues or maintenance activities from MYOB that might be affecting the service. Lastly, verify the configuration settings for the print/email invoices module, as incorrect settings can sometimes cause connection issues. For more troubleshooting, please see this post: Unable to connect
I hope this helps!
Regards,
Earl
