Over the last few days my wife has had a problem accessing this logon page on her PC (budget-level Windows 10 home desktop). When she tries to bring up the ANZ Internet banking logon screen it does not load (i.e. all that can be seen is a blank screen). On all browsers the padlock and web address appear in the address bar. On IE and Chrome the progress indicator (i.e. rolling ellipsis in IE) stays on forever and task manager shows the PC as nearly idle. In Edge the page load shows as completed after a few seconds (i.e. the refresh symbol replaces the cross symbol). So consistent results across multiple browsers, which tends to disqualify browser extensions as a cause.
I have my own userid on that PC and experience the same problem.
There are no problems with any other web page, including other https websites and other ANZ web pages on that PC and no problem accessing ANZ IB from my laptop (on the same home network) - so not a router/internet connection issue it seems. Both hers and my machine run AVG Internet protection software with the same settings as far as I know but I would have thought that if this were a problem it would occur with multiple web pages. That leaves hardware issues - but again what hardware issue would affect just one web page? There have been no hardware changes at all and no driver updates in the last few months that I know of.
So I am stumped. All suggestions on what further to try welcomed
