MFA users storage locked

serban_dogarescu · October 22, 2025, 12:56pm

Hi all,

our Gateway service cannot start anymore due of the following error:

Secure Gateway failed to start System.ArgumentException: An item with the same key has already been added. Key: CORPORATE\bastion.garioni

We have RoyalTS Server v5, with MFA enabled and integrated with Active Directory.

If we disable MFA the gateway starts.

Can you please help ?

Thanks

Serban

Serban,

it looks like you have added the same MFA key to two users. Deleting the duplicate should resolve the issue. If that doesn’t help, I would ask that you open a support ticket here: https://www.royalapps.com/go/support-ticket-new

Kind regards,

Germar

The ticket has been resolved. Updating to the latest version and removing duplicate users resolved the issue.
