[BUG] cannot listen to ipv6

[Cherryblue]

Description

Oxicloud doesn't listen to IPv6 if asked to.
If I set IPv6 environment variables, it defaults to ipv4.
Visible in logs, and ipv6 doesn't access to the app.

To Reproduce

1. configure your reverse-proxy to redirect your domain name to oxicloud pod using ipv6
2. open docker-compose.yml
3. in enviroment category, add OXICLOUD_SERVER_HOST=::1 or OXICLOUD_SERVER_HOST=0.0.0.0.0.0.0.0
4. sudo docker compose down
5. sudo docker compose up -d
6. check logs, see : "INFO oxicloud: Starting OxiCloud server on http://0.0.0.0:8086"
7. web UI is unavailable (502, because reverse proxy doesn't get any reply from pod)

If I reconfigure my reverse-proxy to redirect using ipv4... it works.

Expected Behavior

• reverse proxy configured for ipv6 redirect
• check logs, see "INFO oxicloud: Starting OxiCloud server on http://::1:8086
• web ui available

Environment

• OS: Dietpi on arm SBC
• Browser: Firefox 150
• OxiCloud Version: latest on April 11th 2026
• Rust Version: dunno, I'm using the official docker image here.

Looking into the server host bind path for IPv6 literals. This looks like a normalization issue around OXICLOUD_SERVER_HOST rather than a reverse-proxy problem. Happy to submit a fix.
