Facebook pixel wont recognise

I have tried to set up our Facebook pixel in Hubspot and spoken to a member of their team and they have said there is a bug on Hubspot as all settings from Facebook are correct and when I try and load it I just get the following page which just continuously loads :

Would someone please advise?

Hey @Sicops When you hit “update pixel” what are you seeing? does this happen for your in all browsers? Does this happen in an incognito browser?

Would you be able to capture any network errors you’re seeing (there’s a guide on this here) to see if this shows up with any additional information please?
