Managed to spin up Opencloud on my NAS. I put a host entry in NPM and it seems to be working. From external internet I can log in and upload files with no issues. But whenever I try to reach it through local IP and port, page loads but stays completely blank.
Googling didn’t give reasonable leads. Has anyone had similar issue that they’ve fixed?


Kinda the opposite, NAT Hairpinning allows you to use the external domain and public IP from the inside.
