Connection refused when running example.py, tests

[stefanlenoach]

Hello! Trying to follow the example project here: https://developer.algorand.org/docs/get-started/dapps/pyteal/

When I ran example.py (and pytest) I got the following issue. Any idea what might be happening? Thanks!

Is sandbox running as specified in https://developer.algorand.org/docs/get-started/dapps/pyteal/#install-sandbox?

If yes, can you show the output of ./sandbox up?

[phoenix0508]

see sandbox.log for detailed progress, or use -v.

• started !

I guess there is no kmd server in docker image.

[fabrice102]

It looks like your sandbox did not start properly. You can see that because it does not display the algod version at the end. You can also look at sandbox.log and see the error at the end.

Most likely you are not using the latest version of sandbox.

Please try in the sandbox folder:

git pull

and then

./sandbox clean
./sandbox up nightly -v

If this does not work, please provide the content of sandbox.log and of the above commands.

just wanted to say thank you, I had a similar error for hours on m1 macOS and this solved my issue.
