(SOLVED) OpenVPN - No return traffic to client

Server was updated and rebooted yesterday but after yet another reboot it works. No chages made to config, just a reboot.
Hi all,
I get a strange problem when testing OpenVPN (using OpenVPN Connect on Windows 10 - No local firewall). Connecting client to server works fine and I can ping a Ubuntu server located behind the OPNsense VPN Server.
I can verify incoming pings from VPN client via tcpdump. Outgoing replies are also shown in the dump. But there it seem to stop. I can't verify that packets are actually sent out from the VPN server and the Windows PC aren't receiving anything.
I've tested manipulating rules and NAT but nothing seems to work. If I instead ping my VPN client from the Ubuntu server a log message is created showing that a packet is sent out but it seems like it uses WAN interface (Internet) and IP, not "ovpns1" and tunnel IP.
It feels like an asymmetric routing or NAT problem but since my experience with OPNsense is zero I don’t know how it is supposed to look when it works.
Any ideas?
