any help will be appreciated.

fixed.
frame/config.py
UIC_ADDRESS was wrongly configured.
But anyway , I think we should notice user better message. UX . So I'll left this issue open.

I have the same question, can you tell me how edit config.py? I am not understand this document about portal.https://book.open-falcon.org/zh/quick_install/judge_components.html @diegozhu @laiwei

potal/frame/config.py 里面的地址配置要与 fe/cfg.json 配置相匹配:
仅供参考 (我的是这样解决的 )
potal/frame/config.py
UIC_ADDRESS = {
'internal': 'http://127.0.0.1:1234',
'external': 'http://192.168.0.237:1234',
}

fe/cfg.json
"http": {
"enabled": true,
"listen": "0.0.0.0:1234"
},
