Hi @FarhanKoujalgi 

Proxy IDs on palo alto side are required to mentioned whenever peer end is acting as Policy based VPN because Palo Alto always act as Route based vpn. Now in order to check if proxy id is causing the issues, you should check the system logs by filtering VPN logs which will give you more clarity on the issue. If issue with proxy ids, you will see logs like proxy-id mismatch / negotiation failed when processing proxy IDProxy ID's need to be identical on both VPN peers for negotiation to be successful. 

Apart from that, I would recommend you to verify the Phase 2 IPSEC parameters, routes for the traffic to be routed from tunnel.

 

Hope it helps!
