We have implemented the Hubspot tracking code on our websites. And we have the latest version on our site as of 27 days ago. But today we noticed through our automated tests that your Code is calling an URL which is causing a 404 and then the API fails. You can see these issues on [https://www.esendex.co.uk/](https://www.esendex.co.uk/) ```auto GET https://api.hubspot.com/messages/v2/message/public?portalId=2246691&messagesUtk=1c985514f789c85891f9a6a405969ff3&hubspotUtk=1c985514f789c85891f9a6a405969ff3 404 (Not Found) Initial messages API call failed messageswidgetshell.js:1 ``` How come this has broken and when will it be fixed? In fact, this is also happening on this forum so its suggests there been a release which has broken your tracking script. Many Thanks Ryan ---

Hi, I too have the same 404 error on my website. It’s been fine up until today. Is there an outage with your servers? (PS I can’t click the “Email when someone replies” checkbox, it’s un-clickable!) ---

It does seem to be fixed now. Be good to know why it took so long. ---
