Hello @leighmhart
At this point your Cloudron system has become a black box, and we can not analyse this issue from just forum posts.
Since you have run some nft commands, please ensure that the service nftables.service is not enabled or running.
systemctl disable --now nftables.service
iptables and nftables can be run together, but we do not support this at all and it will cause issues if not done properly.
Reboot your system after that. This should ensure that the Cloudron default for iptables is restored.
If the issue persists, please report back here.
