Hey @James_Neilson2,
Thank you very much for trying out our suggestion 
. I’m only sorry it didn’t work.
Moreover, thank you for going beyond that and sharing more details. It seems that from here on out, you’d be in best hands with our technical team.
I’ve gone ahead and moved this thread in the #support category, so they can take a closer look at what is going on. In the meantime, could you please share some more details about your Core, Network and Setup in general? You can use this article as a guide.
