+```text
+DEBUG : remote: got fatal oauth error: oauth2: "invalid_grant" "Session doesn't have required client"
+```

+have required client", so you may see references to that in older descriptions
+of this case.)

 When this happens, you need to replace the token as described above to be able
 to use your remote again.
