Hi @Ron Deasy
Thank you for reaching out to the community forum!
I understand that you are unable to creating a Cloud Sync Configuration and you are getting an error message "An unexpected error occurred. Please refresh and try again."
When setting up a new Cloud Sync Configuration, if you encounter the error message “An unexpected error occurred. Please refresh and try again,” it could be due to a conflict with an existing configuration using the same agent and synchronization direction.
please ensure there are no other active configurations that might be using the same agent and sync direction. If there are, consider removing or modifying the conflicting configuration.
Please make sure the Cloud Sync agent is installed and running on your server and the agent appearing in the portal and is marked as healthy. Also, check the required ports (80 and 443) are open for outbound traffic.
