OpenID authentication with FTN providers - dependency error

Hello,
I need to authenticate users using FTN and started testing things out using Signicat’s test environment found here:
https://login-test.signicat.io

I setup the OAuth / OpenID client on the dashboard “Api Clients” and was able to set up Postman to request a new Authorization Code and Token flow. The issue is when I change the “Identity provider restrictions” on the OAuth / OpenID client settings to only show ‘ftn’ providers.
When I do it, I am properly redirected to a list of Finnish banks, I pick one, like “OP” and go thru all the forms, but at the end I am redirected to a signicat page that says:

Virhe tapahtui
Ole hyvä ja yritä uudelleen tai ota yhteys tukeen
Pyynnön ID	0HMI4E21SQ574:0000021C
Virhekoodi	IDH_30
Virhekuvaus	Dependency error

I cannot find any info anywhere about what this might be. I would appreciate any help!

Hi,

Thank you for your questions. We have previously responded to you via our support system about this, but I’m happy to share the information here as well to make it visible for you and the rest of our community members.

At the time you experienced the issue, there were some problems related to FTN. However, those issues have since been resolved, and you should now be able to connect without any problems.

Please ensure that you are using the correct OAuth / OpenID Clients, and that you have activated MLE (Mutual Link Encryption) for your setup. You can find more details on how to configure this in the following documentation: FTN Integration Details.

Have a great day!
