I too have never seen the issue on a number of different connections and browsers.

michaelmurfy: I was unable to replicate the issue at all - are all of you experiencing issues on Orcon?

Just FYI I work at ANZ however have no direct involvement with the IB platform. If we can isolate the issue to either an ISP or specific browser build then I can pass it on to the right people to investigate further. Just to further test things could you please also try loading the page tethered to your mobile? I kinda have a suspicion to what may be causing this.

I am using Orcon though their white ADSL Genius router.

I am not sure what you mean by a 'page tethered to your mobile'.  I can use IB without a problem on my laptop but not on my wife's PC.  I had forgotten she has Windows 10 PRO whereas I have Windows 10 Home.  Both of us use Edge as our browser.

Basically I have seen this issue with people who are using DNS unblockers before too along with some Orcon / Slingshot customers and have not figured out what is really causing it. In most cases rebooting the router (which often gets a new IP) corrects it but there appears to be something else funky going on as these people with issues are often unable to access some other websites like Stuff or NZ Herald.

 

This is only based on what I have seen - I have never managed to replicate this on many different connections. My other theory is it could be a MTU issue on the customers end.

 

This problem is limited to accessing the ANZ IB logon page on a particular PC.  Other PCs on then same home network work fine.  On the problem PC I have two users configured and the same problem occurs in both.

I have had the same IP address now for many years.  I am on my third Orcon router (IIRC) and my second Genius router and have always had the same IP address.  Effectively I have a fixed IP address but don't pay for that or need it.

With all of that in mind it's clearly that specific PC or an application on it. Short of a complete reinstall of Windows there is nothing else I can suggest.

It occurred to me that I had not eliminated the home network connection of the problem PC to the router.  I was using a USB WIFI dongle, so I pulled that out and substituted an Ethernet cable connection to the router.  Problem solved - the ANZ IB logon page displays.

So I set about removing the Ethernet cable and putting the USB dongle back.  I decided to try using a USB 3 port (on the basis I may get better network throughput) - but although it connected to the router there was no 'internet access'.  So I moved the dongle to a USB 2 port.  With internet access now restored, the ANZ IB logon page now displays (in Edge).

So normal service is now resumed but I will never know why.  Thankfully a Windows reinstall (the next option) was averted.  I am reminded again why, 10 years ago, I decided to exit the IT industry rather than migrate my mainframe software support skillset to the Windows world

Many thanks to all for your feedback.

Ooops, I spoke too soon - the problem is back. Swapping back to a wired connection no longer works. Rebooting the router did not fix the problem.  back to square 1.  I will explore ANZ IT support options with a view to getting them to look at what is happening from my ip address while I reproduce the problem.

I know that ANZ business banking had different requirements and needed a specific app. If your problem is related to business banking, make sure you upgrade to the latest version.

Also, if you have Java installed, try to delete the Java cache (Control Panel -> Java applet -> General Tab -> Temporary Internet Files section -> Settings button -> Delete files button).

Is it worth trying the browsers in private/incognito mode - just in case there is some cached junk getting in the way?

Probably also worth downloading and running malwarebytes on your PC as well - just to check you dont have some malware doing some bad things.

Whos your isp i had a similar issue with vodafone when the modem received an ip address ending in .255 some web sites would stop working, and anz was one of them.

Tried - alas no change.

I am having all sorts of issues I believe its an Edge problem I cannot types into search boxes or insert info to log on to sites.  If I switch to open with Internet Explorer ( under Settings) I can input info. I thought at first it was a keyboard problem But have just upgraded my laptop to the latest version today 16215 Have the same problem using Edge I can right on a link and add a new tab and things work on most occasions very frustrating

ANZ has gotten rid of the need for Java for ANZ Direct Online. Strange how it was working on Ethernet but not anymore... I honestly don't know what to recommend short of checking your MTU settings. The other thing I mean by tethering via your mobile is to connect to your mobiles WiFi hotspot and testing over that.

Secure pages only 1/2 working is a classic MTU issue. Reduce the MTU (on the client) to say 500 and see if works. Change back to default (normally 1500) and then check your router and see if its doing the right stuff with MTU (Called MSS Clamping or alike).

If you want a boring technical explanation see Problems in: https://en.wikipedia.org/wiki/Path_MTU_Discovery

 Time to get Wireshark out if you really want to see the problem..

Thanks for the suggestions. Changed MTU to 1458, 1430 (as suggested by other websites) and 500 using netsh commands with reboots for each change followed by testing. Problem persists.  Currently trying to get credible ANZ IT folks (i.e. non-help-desk) involved.

Note that my wife has discovered that the IOS version of Go Money is usable, so have that option as well as using IB on another PC.
