We have MFA failures on multiple admin user

Ex: civil-devops and tpaas-devops users.

Authentication is intermittent/flapping. Now, we are unable to login. Is there anything going around within y-lastic ?

    What app are you using for MFA?

    Looking into this. Would you like to disable MFA for this login while we are looking into this?

    Disabled MFA for those three logins. Please go to https://dashboard.ylastic.com/logout and you should be able to login with your password and no MFA.

    Found the issue. Looks like the NTP server used by Amazon Linux has a bit of a drift on the clock. That was causing the MFA code to be invalid as all MFA codes are time based. We made a change to the NTP servers used.

    Please try this again when you get a chance and let us know if you have any issue with MFA.
