I just installed ArcGIS Enterprise 10.7.1 with the Notebook Server. Docker Desktop is running and I also downloaded and pulled the esri docker images (Advanced and Standard). The server is also federated and designated. However, when I click the Notebook on Portal for ArcGIS, it throws this error (screenshot below):
I also added a notebook from Add Item, same error. and when I'm going to create a notebook via Create button in My Content, nothing happens. Any ideas?
