USG40: Can't get port forwarding working anymore

I have used port forwarding for a number of years in a USG20 and a USG40, and they have worked well.

Recently I have added two more port forwards in my USG40, but none of them works. A port scan shows that the ports are not open.

I then tried to delete one of my well working forwards (NAT, SecPolicy, Objects), and created it again. Now this is also not working.

Any ideas what is going wrong now? Soon getting some grey hair from this....

My USG40 has v4.35.

    It finally showed up to be all devices that passed my switch Zyxel GS 1920-24. It was kind of working, but had to be turned off/on to get failing devices to work again. Never seen that before.
