Andy, Thanks for your reply. I think I must have changed the file at an earlier stage indeed. Reverted the nifi.sensitive.props.key to an empty string and it came back up.

The error looks like Jetty cannot start because it cannot decrypt some value from the flow controller serialization (the flow.xml.gz file in $NIFI_HOME/conf/). This could be the proxy password, or a sensitive processor property like a key or password (specifically from your stacktrace, it does appear to be a processor property). Did the flow document change at all? Did you change the “nifi.sensitive.props.key” value in nifi.properties?
