Good morning.
I'm developing a Blazor Server application that requires Okta authentication.
Although I've followed all the instructions, after authentication I still receive the following error message: "OpenIdConnectAuthenticationHandler: message.State is null or empty."
The application runs in https, cross-origin third-party cookies are enabled, and the application settings on the Okta website are consistent with the application code.
Has anyone encountered and solved this problem?

Hi @LucaC.94005 (Customer) , Thank you for reaching out to the Okta Community!
This question is more appropriate for our dedicated Okta Developer Forum.
My advice would be to reach out via devforum.okta.com to take advantage of their expertise.
While we'll do our best to answer all of your questions here, this medium is more inclined towards Okta general questions around core products and features (non-custom/developer work).
I'm not sure the following devforum posts are relevant to your specific implementation, but you can check them out here:
