VAT Reporting - 5xx error

I have been trying to upload my return since last Thursday (January 27th, 2022) and every time I click on VAT Reporting, I received this message - “5xx server error. We’re updating our services. Please try again later”. I could understand this for a few days and especially over the weekend but I don’t believe this is accurate at this point. I am also located in Canada trying to submit the UK VAT return. I’ve done this before but not sure if newer updates would prevent me from uploading my excel file to submit my return. Appreciate any help you could provide.
