I am having a on-premise provisioning agent deployed in a Oracle Linux 7.9 machine and its status is Live and Operational in Okta console. But I receive "There was an unexpected internal error. Please try again." error when I try to add a SWA application that can be connected from the successfully running on-premise provisioning agent. My SCIM Connector application is in local network to the provisioning agent machine. My SCIM Connection base URL is http://192.168.10.48:9000 . This URL is completely accessible from the provisioning agent machine when I use wget/curl command. The on-premise provisioning agent host is having direct internet access (not behind any proxy, but behind a NAT GW). In order to test, I exposed my SCIM Connector application to internet using ngrok and used the publicly expose ngrok URL as base URL for SWA application that uses the same on-premise provisioning agent. Still I receive the same error. Interesting thing is, when I use the same ngrok URL as base URL and Provisioning is SCIM (not using on-premise provisioning agent), everything works fine.

I do not find any logs in the on-premise provisioning agent service and in the system logs too. I disabled selinux in the on-premise provisioning agent machine as keeping it enabled might cause this kind of problems (learned from my personal experience).

I can't expose my SCIM Connector application to internet. I need the on-premise provisioning agent starts working for my SCIM connector application.
