JeffG.56615 (Customer) asked a question.
Has anyone else experienced HTTP 421 Redirect Messages only from mobile IOS devices when accessing Okta sign-on widget? We are hub and spoke OIE configuration and have recently found these messages from mobile IOS devices only. The messages are intermittent, sometimes the message appears then with another access the message is gone.
Is this a possible certification configuration issue?
Thanks for any help.

Hi @JeffG.56615 (Customer) , Thank you for reaching out to the Okta Community!
It could be a certificate issue if you are re-using certificates for multiple orgs with custom domains.
That being said, while I was looking into this I noticed that your organization already has a support ticket open.
We can provide general guidance and documentation, but in-depth troubleshooting is outside of the Okta Community forum scope.
If you already have a Support ticket open, then I recommend continuing the discussion with the assigned Technical Support Engineers. They'll be able to access additional tools and resources to help you get to the bottom of it.
Regards.
