Cant connect to client server via IP Wired VPN provided by ISP through My Local Network

Help , im currently do some work on connecting between 2 sites via Wired VPN provided by ISP.

The connection succesfully estabilished between My local network to Client server using my unused mikrotik ( theres only VPN configuration )

But the problem is when im trying to connect to client server while using internet at the same time with my main Mikrotik , only ping-ing with mikrotik works but using my local network i cant connect to the client server.

When i ping via local and Check the connection running using torch interface Ether7 it only shows Tx while RX still 0

PS :
1.Ether1 Local (10.8.7.0/24), Ether 2 - MainISP, Ether3 - Backup ISP, Ether7 - VPN (172.17.75.138/30) Remote server (172.16.160.0/24)

Please help me , im also beginner in this field
Thanks in advance.
