Hi @anthonint , welcome to the forums and thank you for including your logfiles!
I am sorry for the frustration here. Connection issues like this are difficult to troubleshoot, but I have confirmed that the server is up and running, and (at least as of right now) there aren’t any modeling jobs running on the server.
The model does require a persistent internet connection, so very large runs that take a long time are more likely to run into connection issues like this. If it makes sense for your project, you might also consider subdividing your AOI into smaller areas and running the model multiple times.
