Configurations for proxying radius requests to home-server using TCP

Proxying to homeserver using a TCP connection is causing issue. I am seeing the response from the homeserver, it seems like freeradius running on proxy server is not honoring the response. I have attached the debug logs collected on the proxying server (debug_proxy_server.txt), homeservers (debug_homeserver.txt). I had to trim the logs to focus on issue logs due to limitation in sending attachments more than 500KB. Please advise if any configuration changes are needed on the proxying server to handle the requests without timeouts. Please note, all the homeservers are running freeradius. Regards, Abhilash
