What could be the issue?

Thanks for reaching out @sosella.

A few questions to help troubleshoot the issue:

• does this issue occur in other browsers?
• do Okta org requests executed from Developer Tools Console resolve with the same error? (e.g. .well-known request)
• are there any hosts file modifications in place?

[sosella]

First of all, thank you for responding and taking a look at this issue.

1) The same error does occur in Edge and Firefox Developer Edition, both in Private Mode

Firefox DE gave a different error message:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://dev-`okta-domain`.com/api/v1/authn. (Reason: CORS request did not succeed).

I attached a screenshot of my Security API Trusted Origins page.

2) I don't know how to execute requests from the Developer Tools Console. Which DTC? On developer.okta.com or in the Developer Tools in Chrome, etc.? Could you provide more information, or point me to documentation?

3) The hosts file is unchanged (empty except for the comments section).

Thank you for your assistance with this issue.

@sosella

https://dev-`okta-domain`.com/

This should be your actual Okta ORG URL, such as https://mycompany.okta.com

That was it. Thank you.
