I encountered this issue on my Oracle Cloud instance. ``` $ misfin serve ~/misfin/fusen.nya.je INFO:misfin:Starting misfind v1.3.4 at 2026-05-22 04:50:18.281575 INFO:misfin:OS error: [Errno 99] Cannot assign requested address ``` This is likely happening because the instance does not have its own public IP address. This can be done by adding the corresponding address to 127.0.0.1 and ::1 (or server private IP adress) with /etc/hosts to avoid this issue. ``` $ sudo nano /etc/hosts 127.0.0.1 localhost fusen.nya.je ::1 localhost fusen.nya.je ip6-localhost ip6-loopback ``` However, this requires a [Reverse proxy](https://gitlab.com/cipres/misfin/-/blob/master/docs/index.md#reverse-proxy). Hmm...... Is there any way to fix this structure?
