Hi Team,
We tried to configure one of the app behind Okta Access gateway. After successfully configure the app and tried to access the app, we are keep getting error message Status code 400 The requested host is not being served by this Access Gateway.
May if anyone else had this issue and what is result for this, please?
Thank you
Rajiv Kafle
