APIConnectionError: Connection error.

[TechieHank]

I have installed the docker image and I have tested that my via curl and my API key can talk to Anthropic. When I run the docker container, noVNC starts and I can even browse the web, but when I run a prompt for the API to work, I get this error message:

Thanks in advance for guidance on how to fix this issue.

I had the same error message and found more info in the logs in terminal where I started the container:
httpx.LocalProtocolError: Illegal header value b'<REDACTED> '

Turns out I had a trailing space when I pasted my API key.

[TechieHank]

@rvadhavk - Thanks for the feedback. I prune all my containers from docker and re-ran bash script without any trailing spaces. Unfortunately - the same issue is happening :( - I did tried to do a sudo apt-get update inside the docker container and it started complaining about a certificate.

@TechieHank are you on a network that has a firewall/proxy that re-encrypts traffic?

Regardless, I updated the latest image with a more verbose error log - can you post the traceback after doing a docker pull ghcr.io/anthropics/computer-use-demo:latest and restarting your container?

Are you using an intranet?
I may have the same problem as you, but I also had a Connection Error and the problem was with the certificate. So I updated the certificate and it was fixed.

@x5a - Here's the Traceback after doing an update of the image:

anthropic.APIConnectionError: Connection error.

[TechieHank]

Are you using an intranet? I may have the same problem as you, but I also had a Connection Error and the problem was with the certificate. So I updated the certificate and it was fixed.

Thanks for the feedback @moo1o - What command did you use to update it? I assume you did the update inside the container Debian VM?

[moo1o]

@TechieHank
I succeeded by following the steps below.

1. Access api.anthropic.com, check the valid certificate information, and extract it.
2. Check the certificate location on your PC with pip show certifi.
3. In the certificate location, paste the certificate information extracted in step 1 at the end of the cacerti.pem file.
