I am having the same issue. The only time that it worked is when i had a fresh Splunk install on windows and installed the add-on. I tried to upgrade the add-on on our linux servers and it did not work, I even tried fresh install of the add-on and still stuck at loading, and creating the inputs on the backend causes 500 server error when loading the UI. I wonder if @jconger have any recommendation. Thanks. UPDATE: I have a standalone instance where the app is working, and there I see that there are python processes (related to this app) that are connecting to hostname:PORT, but in the instance where the app is not working, it is not even attempting to connect. The connection and port is open but there are no python processes at all. Not sure why the app is not even attempting to connect.
