and sometimes it gave
cannot verify the codes, please try again later

and when going through audit logs it seems there is a slight frequent failure
Activity Type- Issue a SAML assertion to the application
Status-failure
Status reason- There is a problem with the service.

It is happening occasionally. Sometimes it works fine. What could be the issue?
