I am also having this same issue where it cant reach the page, so clearly there is a problem. My workaround is to do it without delcaring then go to payroll reporting and submit from there as previously mentioned in this thread. There has to be a reason why its stopped working in the last week. MYOB not connecting via that webpage. I dont want to have to manually declare payroll each week since I have quite a few, just time consuming and an extra step. If anyone gets a resolution please comment. I dont believe is to do with the firewalls as we havent touch this in the last week.
