Hello Prefect Community, I posted my error message (when connecting to Prefect UI from CLI) to Prefect UI. Posting the same here to see if someone can help. I am trying to configure Prefect CLI in my entrypoint.sh file - loading the config with all variables like prefect workspace, api key etc. Then when I try to do the following: # Configure prefect CLI to use server backend echo "Configuring Prefect2 CLI..."

prefect cloud login --key "$PREFECT_TOKEN" --workspace "$PREFECT_WORKSPACE"

echo "Done configuring Prefect CLI." Prefect Cloud ENABLED... Successfully parsed PREFECT_TOKEN (not displayed) Configuring Prefect2 CLI... I get the following httpx connection timeout error: Traceback (most recent call last): File "/usr/local/lib/python3.8/site-packages/httpcore/backends/asyncio.py", line 114, in connect_tcp stream: anyio.abc.ByteStream = await anyio.connect_tcp( File "/usr/local/lib/python3.8/site-packages/anyio/_core/_sockets.py", line 192, in connect_tcp gai_res = await getaddrinfo( File "/usr/local/lib/python3.8/site-packages/anyio/_core/_sockets.py", line 511, in getaddrinfo gai_res = await get_asynclib().getaddrinfo( File "/usr/local/lib/python3.8/site-packages/anyio/_backends/_asyncio.py", line 1690, in getaddrinfo result = await get_running_loop().getaddrinfo( File "/usr/local/lib/python3.8/asyncio/base_events.py", line 825, in getaddrinfo return await self.run_in_executor( asyncio.exceptions.CancelledError During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/local/lib/python3.8/site-packages/httpcore/_exceptions.py", line 10, in map_exceptions yield File "/usr/local/lib/python3.8/site-packages/httpcore/backends/asyncio.py", line 121, in connect_tcp stream._raw_socket.setsockopt(*option) #

[3:51 PM] However, if I run the same command in the same powershell terminal with the actual token and workspace, it is connecting to prefect cloud without any issues.                                                                                                                                                                                                                                                                  prefect cloud login --key "$PREFECT_TOKEN" --workspace "$PREFECT_WORKSPACE"

[3:52 PM] Can you please help me with this connection timeout issue? Using Python 3.8, Prefect 2.0 cloud [3:53 PM] I do run this in my venv. [2:58 PM] Can you please suggest some fixes for this httpx connection timeout error?

hmm, are you sure that your powershell script is using an environment where your PREFECT_API_URL and PREFECT_API_KEY are set? I could see how timeout errors would make sense if your API url was wrong / not set

Thanks for looking into it Nate! The powershell script is just launching the CLI command "prefect cloud login --key "$PREFECT_TOKEN" --workspace "$PREFECT_WORKSPACE"". I gave this command in a separate powershell prompt (giving my actual workspace name and API key) and it worked! But not in the script.

you can just set / export the API key and API url without an actual login tot he same effect

Sorry, ignore what I mentioned about pwershell. It's just bash. I can use the API URL. But how do I invoke the URL from my bash script? What command do I pass? Thank you so much for your help!

you can just set / export the API key and API url without an actual login to the same effect

as chris mentioned, I think you probably don't need to run a script to do a login at all. you just need to set 2 environment variables: • PREFECT_API_KEY • PREFECT_API_URL any subsequent prefect operations will find and use these credentials to communicate with whatever workspace is indicated by the API URL you set

export PREFECT_API_KEY=<value>

and same for API_URL
