In order to ping any destination , first of all you need to check routing table by show ip route if destination is there. After that check on remote device’s routing table and make sure they have path for each other in the table , then do further troubleshooting accordingly

What is your topology, can you share it please.

Try pinging using source which has been advertised in BGP (Logic - You can ping your BGP learnt routes from the Network which is advertised in BGP - Source in this case).
Just check if you have advertised the subnet in BGP from where you are trying to ping.

Above 2 should clear your doubts.
