OPEN VPN server not respond to client

[sleepydragon]

hey all,

I setup an open vpn server on my opnsense box, my phone and laptop has no problem to connected to it, however, my wife ( she is back in China) can't connect to the vpn server.

i did dns resolve on her laptop, IP address comes out correctly. i can see her connect request on my firewall, with a public IP and random port number, and is permitted. when i troubleshooting, every time i reset the server config and switch to a new port, she can connect at the very first time, then server will not respond to the request anymore, my phone on cellular network works every time.   

hope anyone can help me with is issue.


below are the log file copy from her client (i * out the IP address of my firewall.):
