On nextcloud 31.0.9 and updated OpenID Connect app to 8.1.0. Immediately after update I am unable to login using my Identity provider.
Note, this has always worked before with this EdDSA algo set in my identity provider. The update broke it.
Why would OpenId Connect stop supporting this more secure popular algo?
To reproduce, use EdDSA algo and click the login with your identity provider button. It prompts for my passkey, then displays error page:
