Try to change https://aus2.mozilla.org to https://aus3.mozilla.org in the pref app.update.url on the about:config page if that pref shows aus2 in the value.

To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
Filter: app.update.url
