Stream Analytics Query UI portal: Unable to connect to input source at the moment

Question

I followed the link below, and created an input, like below:
https://learn.microsoft.com/en-us/azure/event-hubs/event-hubs-tutorial-visualize-anomalies

The Test button in the red box confirms the connection is ok.

However, on the Query page, it shows error below:

Unable to connect to input source at the moment. Please check if the
input source is available and if it has not hit connection limits.

Below shows that the incoming messages are already in the event hub.

I tried using both Connection String and MI for the input, but am still getting the error.

I can send messages to and receive them from the event hub by following the link below:
