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 https://github.com/nextcloud/nextcloudpi/wiki/How-to-access-from-outside-your-network 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.
