MYOB Employer Services - "Unable to Connect" message on using "Get Software Identifier" and STP submission process

Hi,

A client recently had an issue where they received a 403 unauthorised message when trying to submit STP to the ATO. I found a question I posted a couple of years ago that was resolved by upgrading MYOB Employer Services to the latest version, so I did the same for this issue to renew the certificate.

After this upgrade, the certificate has been upgraded, so the authorisation error has gone away, but they are now getting an Unable to Connect error (Code 0).

I have tried following the steps in this article but I can't seem to get this resolved. STP has been submitted from the computer/server in previous years, and now has stopped working since August 2024, which they only just noticed.

Could this issue be related to the computer/server itself, or is it worth trying to do another upgrade or re-install of the MYOB Employer Services software?

They are hoping to have this resolved before the financial year ends, so any advice on this would be appreciated.

Let me know if you need any other information.

Kind regards,

Andrew
