Hi
I am trying to use following article to get ADFS working with Azure AD B2C in the start almost 3 weeks ago it worked and now I am getting this error.

https://video2.skills-academy.com/en-us/azure/active-directory-b2c/identity-provider-adfs2016-custom?tabs=app-reg-ga

The error that I am getting is

"AADB2C90168: The HTTP-Redirect request does not contain the required parameter 'Signature' for a signed request."

I removed my Custom policy and took on a vanilla policy from starter pack and configured ADFS but had same result.
There is no guidance on AADB2C90168 on the Internet on this error.

The ADFS is using a Public certificate and AzureAD B2C is using self-signed certificate (as described in Pre-Requisite section).

Any help will be appreciated.

    Hi @SaqibAhmed-1948,

    Have you tried to update a federation metadata?

    Is your public certificate still valid?

    In Server Manager, select Tools, and then select ADFS Management.

    Select the relying party trust you created, select Update from Federation Metadata, and then click Update.
