Help fixing invalid origin with memos (lemdro.id)

Running joplin and memos in docker, routed through nginx. Since I don't own a domain I'm just using my public ip with ports and port forwarding. Joplin was throwing the same invalid origin error, but worked after I set APP_BASE_URL: http://<IP>:<port>. I tried setting SITE_URL=http://<IP>:<port2> under environment, which I've read is supposed to fix this exact problem. Same error. The error displays the correct address including port number, so I know that's being passed correctly. I've tried several different variations of the Host, Origin, and Referer header without success. Just for fun I tried directly exposing <port2> on the memos instance and it opened right up in the browser.

PS: Yes, I know I should be using https. I'm lazy. Setting up a cert is on the old todo list.

There's no reason not to expose those services to the Internet, they have authentication, and noone can access them without logging in first. There are actually reasons for exposing them, you can share a memo or a file to other people. You should enable HTTPS though to prevent passwords being transferred in clear text.

You assume there is no vulnerability in the web server itself, or a vulnerability that allows bypassing authentication.
