Unable to authenticate after upgrade

I updated (actually removed and installed) to version 2.3.5 of njstuya and 1.07 of cloudtuya and now I'm getting the following using the same user-id and password. Before upgrading I was just getting the can't auth twice in 60 seconds error. FYI: it would be nice if an upgrade preserved the old key.json file so that it would not need to be recreated.
