Error in wait_for(function() mlflow_rest("experiments", "list", client = client), : Operation failed after waiting for 10 seconds

Hi there,

I experienced the error "Error in wait_for(function() mlflow_rest("experiments", "list", client = client), : Operation failed after waiting for 10 seconds" on running mlflow_set_experiment("Test"). What happened?

Start by reproducing mlflow_set_experiment("Test") with mlflow 1.10.0 on R 4.0.2 and Windows 10, then inspect the mlflow_rest("experiments", "list") call and its wait_for timeout. Done means identifying the cause of the failed request and documenting or validating a concrete fix.
