Hi @StephDotNet

Have a look on this forum and there are suggestions: [The key authorization file from the server did not match this challenge](https://community.letsencrypt.org/t/the-key-authorization-file-from-the-server-did-not-match-this-challenge/13566)

letsencrypt-vista is developed by a third party and you should be able to review issues or log a new one with them [https://github.com/interbrite/letsencrypt-vesta](https://github.com/interbrite/letsencrypt-vesta) (this is probably the best way forward as it is most likely a client related error)
