Is there an existing issue for the same bug? (If one exists, thumbs up or comment on the issue instead).

• I have checked the existing issues.

I'm guessing you followed the getting started guidelines here: https://docs.all-hands.dev/usage/local-setup

Just going to gentle ping @llamantino. They have been really awesome with helping people with startup issues.

[edward1987]

i have folowed the docs , the problem apear in the container created for agent

[llamantino]

Unfortunately, the stack trace only includes frames from third-party libraries, so it's not enough to understand what’s going wrong.
Could you please share a more complete log, and let us know exactly what you were doing when the issue occurred? Thanks!

[kmccabe87]

i have the same issue, same setup.... docker desktop wsl 2 win 11

[llamantino]

@kmccabe87 thanks for confirming that this might not be an isolated issue.

The log shared above so far doesn’t point to anything specific - it just shows a generic error from a third-party HTTP library, so we’ll need a few more details to investigate. Could you include the full log, if possible? (please double-check that it doesn’t contain any personal information)

We need also some steps to try and reproduce the issue:

• How did you start OpenHands?
• How did you configure it?
• And what were you doing when the error occurred?

I’ve tested OpenHands 0.48 on Windows with Docker and WSL2, and it seems to be working fine on my end.

[edward1987]

that is the full log , the error is in the agent container created by openhands that was running on docker windows wsl 2.

at this point i remove all containers and installed on the system ( no docker ) and there is no more error, so the problem is only when using docker on windows system ( docker desktop ) .

i was getting that error every time i was starting new conversation, exacly after installed dependency.

[llamantino]

@edward1987 Thanks for following up. I did a quick check and I'm seeing the same error in the agent/runtime container logs. On my end, though, the agent still works fine, so it doesn't seem to be a blocking issue. I think I've already seen it before, and it's likely harmless. I can also confirm it happens on the 0.45 runtime as well.

Just to clarify, when you saw that error, did the agent keep working, or did you run into other issues? Was there a specific reason that led you to check the runtime container logs?

I managed to reproduce the same behavior on Ubuntu too, so it doesn't appear to be Windows-specific. It seems more related to the Docker workflow itself.

I've included the full log below for reference. Let me know if it matches what you're seeing.
