Guest WiFi suddenly cant access Login page

I've had a call from my client saying that guests are unable to access the captive portal login page all of a sudden. It has been working for a few months without issue.

I have been to site and checked the internet connectivity which is all fine. I have tried resaving the configuration on the guest pages in CNMaestro by hasnt helped.

I have attached a screenshot from my phone, the portal url doesnt look correct to me?
