Unable to access one website

markcaldwell83 — Thu, 03 Oct 2024 09:47:39 GMT

Hi,

I have previously been able to access https://www.pkbstatus.com/ without any issues until today

The issue seems to be with my wifi connection as when I connect via my mobile network it works fine and other members of my team at work can access it without any problem.

I have also tried different browsers, clearing the cache but nothing seems to be working, do you have any suggestions?

Kind regards, Mark

What DNS server are you using? @markcaldwell83

Is that the IP address listed under my plusnet wifi connection?

Um...

Yet another medical site that somebody cannot access. There seems to be a recurring theme here.

I seem able to access it without a problem.

Assuming you are using the Hub2 the DNS settings can be found here (after logging into the router).

I have the DNS to Google's but within Windows.

8.8.8.8
8.8.4.4

Good morning, thank you very much for the replies.

I'm on hub1 but found the DNS settings although no idea what they mean or how to check if they are correct or if they've changed.

Primary DNS:	212.159.13.49
Secondary DNS:	212.159.6.9

Those are the settings I have in my Hub2 but, as I said, I have changed them to Google's within Windows.

How you change them I think depends on which Windows version you have.

On W10 Click on Control Panel then Network and Sharing Centre. In the resulting page click 'Change adaptor settings'. Select your network connection from the list then click on 'Change settings of this connection'.

A new window opens and within the Network tab scroll to and double-click on 'Internet Protocol Version 4 (TCP/IPv4)' At the bottom of the next window select 'Use the following DNS server addresses:' then enter 8.8.8.8 as the first then 8.8.4.4 as the second.

Hi Mav,

Thanks again for your reply.

I'm on a mac but just had a few questions before changing anything if that's okay;

1. If I change to the google DNS server addresses is there any risk I won't be able to connect at all?

2. Do you know why all of a sudden those DNS settings I currently have would all of a sudden stop one website from working?

Re: Unable to access one website

Mav — Fri, 04 Oct 2024 13:59:59 GMT

To answer your first question I always change the DNS servers to Google's when ever I have a (re-)installation of Windows and have never had any issues accessing sites other than those outside of DNS problems.

I can't answer the second one, sorry.

Your problem seems very similar to my own Plusnet DNS Issues - Plusnet Community

Your site works for me using 1.1.1.1 (Cloudflare) but not 212.159.13.49 (Plusnet). I've not checked any other DNS servers though. Mine doesn't resolve on any of the Plusnet or BT DNS servers, or EE mobile.

You can change your local DNS to something like 1.1.1.1 (Cloudflare) but this isn't going to help anyone else using BT / Plusnet or EE to connect to your site.

Personally, I'd recommend not changing it otherwise you won't know when the issue is fixed, unless of course you need to work on the site. It should work via a VPN as well.

I can also access the site and am also using the Cloudflare DNS servers in Windows.

Morning all,

Still no luck, thanks for all the feedback.

@Starlink666 in the end did you make changes or did plusnet, I read through your thread but got a little lost in parts so wasn't sure if in the end it just mysteriously started working?

Wondering if I need to escalate to plusnet, I'd prefer to not go changing settings at my end as it was working just over a week ago so why not now?

And it's an important site I need for monitoring in my job so wondering how to escalate with plusnet.

Any advice and guidance again is greatly appreciated

@markcaldwell83

It is possible to configure a browser NOT to use your local DNS.

For google, settings, search for DNS, then Security, I changed to OpenDNS

For Firefox

Search for DNS I used

I now can see the patients knows best stats page, this should help for the short term.

Hi Dan,

Just tried that in Firefox and that works which is great!... didn't know you could do that.

So the DNS settings can just be changed at browser level, as long as it works I don't mind.

I just was wary of changing settings that would affect my girlfriend as we both work from home and I don't want to cause any issues for her

Dan_the_Van — Thu, 10 Oct 2024 07:17:19 GMT

Yes, the change is to the browser only, if you used Edge/Chrome then the issue would still exist.

The plusnet DNS issue still needs resolving maybe @willcutforth can help?

Dan.

Thanks again Dan.

Yes my primary browser is Chrome but good to have the Firefox option for now

@markcaldwell83 - I changed everything over to Cloudflare at around 9am Monday morning. At 3pm the BT / Plusnet DNS servers were still not resolving my website. All other DNS servers had propagated and were resolving fine. I think it was around 5pm the BT / Plusnet DNS servers starting working. I know it had been escalated and was being looked into, so I'm not sure if they resolved it or swapping to Cloudflare fixed it. If I was to guess, I'd say someone fixed the issue and swapping to Cloudflare made no difference. I'd already swapped the nameservers (on same host) before without any joy.

@Starlink666 I'm using Plusnet's DNS servers, your site is not available....

Re: Unable to access one website

Starlink666 — Thu, 10 Oct 2024 13:18:27 GMT

@Champnet Strange. It's working for me and everyone I asked to test it who couldn't access it before. Which DNS sever are you using exactly?

Re: Unable to access one website

@Starlink666 Cache has been flushed
