Public Wifi - Page to enter credentials is not loading

Hi There,

I am using a public wifi network as I am away from home. I had previously bought 30 days access which had its on credentials to capture before the final connection to the hotspot was made. I have now purchased a further 30 days access and that has come with new credentials. When I select the network it says it is connected etc but the page to input the new credentials will not load and I am unable to use the internet as it says I am not connected whenever I try to load a site.

I have tried a variety of things so far:

• laptop off/on
• wifi off/on
• clear DNS
• use apple captive address - it just tells me I'm not online and doesn't seem to search out whether there is a captive requirement.
• rebooted in safe mode and repeated all of the above.

I'd welcome any other suggestions people might have.

I'm actually not a computer expert but I can usually figure things out/ follow instructions so I'd be really grateful if responses were kept simple.

FYI - I'm having exactly the same issue with my iPhone.
