client get not connected in pfsense openvpn site to site

Solution 1:

Guessing maybe you still have block private networks enabled on WAN? If you're connecting in from 192.168.1.x at least, and WAN is really a LAN in your case.

On an unrelated note, it's always preferable to use UDP for VPNs unless TCP is required for some reason (can't pass UDP between client and server).
