Custom Domain With Wildcard Certificate

Can i use a wildcard certificate with Okta or do need to buy a custom certificate for the subdomain?

I’d like to use a subdomain like my.example.com where i have a wildcard cert for example.com

Thanks in advance!

Did you figure this out? I cannot get our wildcard working with the custom URL.

I haven’t found a solution. Are there any Okta support folks that could help us out?

Anyone figure this out?

I tested it in a dev tenant and it shows an error that the CN on cert much match the domain specified so I would assume at present wildcard certs are not supported. I note however that Okta Identity Engine (https://www.okta.com/okta-identity-engine/) has support for multiple branded subsidiaries so perhaps they will support it when that feature flag is GA
