Setting up new eTax account via MyNumber link not working?

I've been working at this since yesterday and each time an error occurs right after the page that confirms all my information. I'm not sure what to do at this point; might go over to my local tax office tomorrow but wanted to see if folks here have similar experiences, or a view?

Context is that I need to set up sole proprietorship as I will be receiving payment for my services as a freelancer. Really hope there is something obvious I am missing that would let me set this up online…
