Can't reach NS&I login page

[#1]

Yesterday I tried to login to my NS&I account but the link to https://secure.nsandi.com can't be reached and the windows diagnostic tool on my computer said I should contact my ISP

I have rebooted my router and added the site as an exception in my Bitdefender dashboard. Still no luck.

I can reach the page on my phone, but only if I switch from Wi-Fi to 4G, which does suggest it is something on the PN side.

Is anyone else having trouble with this?

PN: Can you sort this out please?

@Clarissa 

I've just tried using the link,  not working for me either, works fine on mobile data.

@Clarissa I don't think it is 'on PN's side' - I can't reach it on a Zen connection either, and they use totally different DNS servers (their own).

Thanks for checking

OK that's interesting. Thanks for checking.

Try the NS&I home page, then click on "Log In" in the top right corner:

https://www.nsandi.com

I did. It doesn't work anymore over normal use of the internet.

I used to be able to access the login page. I have been accessing this site for years, and always using PN internet. But it doesn't work today, or yesterday.

I have found I can get in via a VPN, as well as 4G.

Not sure what to do. The diagnostic tool said my computer is configured correctly, so reluctant to make changes to router or firewall settings my side.

Just a thought - wonder if NSI&I have changed the IP for that page and it hasn't worked its way to the DNS servers yet?

I doubt it's a DNS issue as nslookup resolves https://secure.nsandi.com to 157.203.60.156 on my plusnet connect and mobile data

The site does not respond to ping, you can login using mobile data.

[#10]

Any idea how long it would take?

[#11]

What does "the site does not respond to a ping" mean?

[#12]

@Dan_the_Van Strange - I can get the login page up if I go via the home page, but get this response (on FF), if I click the 'secure.nsiandi.com' link in the OP.

Edit to add the response from the OP link:

[#13]

@jab1 

I get the same as you on my Plusnet FTTC connection.

Same result here.

Possibly not what you want to hear, but if you can get access via a VPN and others are experiencing the same problem, just do nothing, sit back and relax, and wait for things to sort themselves out.

At least NS&I won't have gone bankrupt!

@Clarissa 

To clarify, are you not able to log in via the link on NS&I's home page?

https://www.nsandi.com

That works for me, on Plusnet broadband, but https://secure.nsandi.com does not.
