On your on-prem router is the BGP neighbour with AWS in the established state? If not check if the BGP authentication password is set correctly and the peering IP are correct and of course your ASN . You need to check from these settings under the virtual interfaces from Direct Connect services menu.

Hi, this blog post details BGP routing setup between AWS cloud and on-prem routers: https://aws.amazon.com/blogs/networking-and-content-delivery/creating-active-passive-bgp-connections-over-aws-direct-connect/

Additionally, the ref doc is here: https://docs.aws.amazon.com/directconnect/latest/UserGuide/routing-and-bgp.html

Finally, this video details how to troubleshoot Direct Connect BGP issues: https://www.youtube.com/watch?v=jkBL_XygQ5w

Best, Didier
