NAT Traversal not working anymore

I have been using SoftEther since 2012 and I think it is great. I have always forwarded the ports at the server site so I always connected with out any issue.

Some times when I do router firmware updates I forget to reset my port forwarding but the client would connect anyway because of the NAT Traversal.

However, I noticed that NAT Traversal no longer works. If I don't forward the ports I get an ( error 1) and can't connect.

Did the software change?

SoftEther VPN doesn't change the operation of NAT-T.

What did NAT-T stop working on?

It stopped working on a SE client (WIN 10)that tries to connect to a SE VPN server (Win 10) that has no ports forwarded on the Firewall/Router

If you specify the destination hostname by IP address, please try using DDNS hostname.
