OpenCode Web UI Times Out (opencode serve)

[cyberluk3]

Hi there,

While greywall --template opencode -- opencode works perfectly fine, I cannot make the OpenCode web UI version work (opencode serve). The page times out whatever I try.

I added the following config in opencode.json:

…
  "network": {
    "allowLocalBinding": true,
    "forwardPorts": [4096]
  },
…

Here are the full command as well as the OpenCode logs:

$ greywall --port 4096 --template opencode -- opencode serve --hostname 0.0.0.0 --port 4096 --print-logs --log-level DEBUG
