External access to Nextcloudpi

Struggling with external access to my Nextcloudpi.

Access via LAN is fine on web GUI.

NextcloudPi version v1.52.4
NextcloudPi image NextCloudPi_RaspberryPi_v1.52.2.img
OS Debian GNU/Linux 11. 5.15.61-v8+ (aarch64)
automount yes
USB devices sda
datadir /media/USBdrive/ncdata/data
data in SD yes
data filesystem ext2/ext3
data disk usage 2.9G/59G
rootfs usage 2.9G/59G
swapfile /var/swap
dbdir /media/USBdrive/ncdatabase
Nextcloud check ok
Nextcloud version
HTTPD service up
PHP service up
MariaDB service up
Redis service up
HPB service up
Postfix service up
Internet check ok
Public IPv4 xx.xx.xx.xx
Public IPv6 not found
Port 80 closed
Port 443 closed

One strange instance is that I have several times tried to set a static ip nc-static-ip but it seems to revert back to it’s dynamic one.

Router has ports forwarded (80 and 443) to the .13 address. I am using noip.com and the IP / Target is the same is on the NC System Info.

Finally netstat -tulpn output from my ssh access:

Active Internet connections (only servers)

Any clues on where I’m going wrong?
