This was caused for me by the line (pyspark):

children = [f for f in dbutils.fs.ls(node)]

with the node being a

"dbfs:/mnt/lifestrategy-blob/scada/"
and this a mounted directory. It seems like the implementation of dbutils.fs is done with the same quality one is used to from databricks... the absolute minimum and very unstable. Could you please manage to renew the token?!
