Cannot open my diagram, web-based Camunda Platform 8

Hi,
I’ve created a project and my first diagram within it.
Now I cannot open this diagram and got only the system message “Waiting for modeler.cloud.camunda.io”.
What should I do next?
Thank you in advance!

Can you explain how you built the model exactly?
Also can you upload it here?

Hello Niall,

I’ve used drag-and-drop functionality of the platform, just modeling, no execution modules. How to explain this?

I cannot upload the model, as I cannot access it.

Probably, these console messagges will help:

Thank you in advance,
Alexander

So you modeled this process in the Camunda Web Modeler?
Now when you try to open the model it causes an error?

Niall, yes, exactly.

It also happened to me…
I was able to open some of the diagrams and some not.
Any explanation or advise what can I do?
