Check below:

1) Compare ODI Master Repository connection detail between ODI Studio login and ODI Agent. They should be connecting as same DB username@the same database.

2) If they are using the same database connection detail but the same problem persists, it may be likely that ODI Repository might have just been renumbered, restored or cloned so the repository signature has been changed.

To overcome the issue, ODI Agent should be bounced so that you can logout and re-login to your ODI Studio and re-test the ODI Agent.
