Hi there, mark.
Let me ensure you can submit your NEST and FPS within QuickBooks Online (QBO).
The Government Gateway credentials entered are typical causes of the rejection. Either it's unactivated yet, or the entry was inaccurate.
See this article for details on how to activate your credentials: Turn on RTI reporting to HMRC in QuickBooks Online Standard Payroll
Once done, follow these steps to check if the entered Gateway credentials are correct:
Furthermore, check out the following articles to view all your submitted FPS and EPS. Also, learn more about NEST submission:
You're always welcome to post your concerns about NEST and FPS submissions here in the Community. Leave one in the comments, and I'll be sure to get back to you.
Thanks RoseJillB, I have followed the instructions again however it still is not working and resulting in the same error.
I have logged into government gateway with the details I have input and so I am clear that they are correct

Hello Kat1001, thanks for joining this thread - we're sorry to hear you've been having ongoing trouble with this. Are you using the Standard or the Advanced version of QuickBooks Online Payroll, and do you have any overdue FPS or EPS submissions showing in QuickBooks?
An EPS will be classed as overdue if it isn't submitted by the 19th of the following tax month. As the EPS report is cumulative, you can delete an overdue EPS to remove this, and then submit the next available EPS once this is produced.
As I don't want to explain my issues over and over again, please don't worry. My case has already been escalated to the Qickbooks Senior Customer Success Expert Team. As I said, I've been in contact with Quickbooks for more than 3 weeks about this. I was just wondering if the original author was able to get this fixed.
