Get online support

Unable to load 1 particular site.

I have 1 particular clients website that I can provide in a private chat that I cannot access from 1 address. I have 2 TPG accounts on NBN 50 at 2 different addresses. Both have been unable to access this particular AU website for some time now. TPG support advised me everything fine on their end.

 

I can access the site on mobile data.

 

To prove a point I just moved 1 address to Aussie Broadband and the site now works at that address so it is definately a TPG issue.

 

If I cant gett he issue resolved I will need to move the other address to Aussie Broadband as well.

 

Any help would be appreciated as no one on the tech support line seems to care.

Hi @kohako . Do you have a Windows computer to try this via TPG account?

Open a command window and do these commands using the problem website.

E.g.

nslookup a.b.c.au

Does it return an ip address? Which DNS is shown?

 

nslookup a.b.c.au 8.8.8.8

Does it return an address using Google dns?

 

For comparison, do the commands on a computer via the ABB account.

 

Out of interest, how long did it take to changeover to ABB?

@kohako . Your PC and Mac might be configured differently regarding DNS. I don't need to know the website name or its ip address, just which commands gave its address and which didn't.

The TPG DNS might not have your website listed, whereas the DNS used by AussieBB and your mobile data does.

 

nslookup a.b.c.au  uses the default dns which could be dns1.tpg.com.au.

nslookup a.b.c.au 8.8.8.8  overrides the default dns to use Google dns.

You can set a DNS override in Windows and Mac, or in the router for all your devices.

On the windows computer I am not getting a dns for nslookup a.b.c.au 8.8.8.8 ( This browser shows the website though)

On my mac I am getting a DNS for both commands. ( Not loading the website)

 

Both on the same wifi channel on TPG account with issue.

@kohako . On the Windows computer, when you do nslookup a.b.c.au, what dns is shown?

This is the dns that the browser uses for the website. Working on Windows.

nslookup a.b.c.au 8.8.8.8 doesn't give the ip address of your website. This means Google hasn't listed your website, which is strange.

 

On the Mac, you say both commands are giving the ip address of your website?

What DNS is shown when you do dnslookup a.b.c.au?

 

I don't see how the command with 8.8.8.8 can work on one computer and not the other.

Hi sorry I was on a VPN on the windows computer. I have turned that off and now same tests on both mac and Windows. Both tests you asked are showing an ip of 122.201.127.227. Both systems are not loading this website. ER_Connection_timed_out

@kohako . The website is known in both DNS. It has ports 80 and 443 open.

I am using Win7 and Chrome. Starting from Google home page, I get the screen below.
