[SOLVED] openvpn - unable to do ssh using openVPN to another EC2

Issue

Architecture( within SAME ACCOUNT)-

1. OpenVPN is present in VPC A (10.41.0.0/16) and was configured using AWS marketplace in region ap-south-1.
2. Another instance "test" is in VPC B (10.40.0.0/16) in a different region ca-central-1
3. There is a VPC peering between VPC A to VPC B and vice versa

Current Situation

1. I am able to ssh into OpenVPN instance and telnet to "test" at 22 is working which indicates that peering is working as expected

Problem

1. When I connect to the OpenVPN server and then try to do an ssh to "test" EC2 instance in VPC B, I am getting a timeout error at port 22.

Things I have tried so far

1. Check telnet at 22 from VPC A to VPC B
2. Verify NACLs, Route tables, security Groups for port 22 in both the VPC ranges

I am unable to figure out the issue, If somebody has worked on this and could help me debug this issue would be really appreciable. Thanks
