NextcloudPi (plus) cant access from outside network after 4 day downtime

So I have been running succesfully my raspberrypi nextcloudpi for nearly a year now. We had a renovation in our house so I pulled the plug from all devices. Now when i came back after 4 days and connected everything I can not access my nextcloud from my freedns domain anymore.

Everything works fine with https://nextcloudpi.local and I have a static IP for nextcloud in my router and i can access it fine with puttys saved IP for it. Ive restarted all devices multiple times and run again everything from here. But still no help. What could be the problem?

Fixed. I ran the portforwarding command a third time and now it somehow works again.
