Hey Arjit P., thanks for reporting. It kind of looks like you might have two separate processes running Phoenix. Can you try to kill all running Phoenix processes, confirm that you cannot access the Phoenix UI, and try again?

My phoenix UI is not accessible as soon as my agent completes the run. I did check processes and couldn't find any running after my program has completed its run.

What OS are you running on?

Looks like Windows

Yes, it's Windows 11, version 23H2

Can you try running Get-Process | Select-String phoenix in PowerShell?

I want to check if there is more than one process running Phoenix.

No results.

If you try to spin up Phoenix, you immediately see that error?

It's at the end, after all my agents have completed its run

Thanks for the clarification. It sounds like you are using Phoenix locally. How are you launching it?

Yes, I am running it locally. Referring to this collab notebook: https://colab.research.google.com/github/Arize-ai/phoenix/blob/main/tutorials/tracing/crewai_tracing_tutorial.ipynb I have attached my code for reference as well

Thanks Arjit P.. So it sounds like you are launching Phoenix using px.launch_app? If I had to guess, Phoenix is probably being started multiple times if you are re-running a notebook or script. If you are running locally, can you try launching Phoenix with phoenix serve from the command line rather inside the notebook?

Sure, will give that a try.

It works now. Thanks a lot Xander, have a great day
