RT 求助坛友了

反向代理的配置是这么写的

#PROXY-START/
underscores_in_headers on;
location / {
    proxy_pass http://127.0.0.1:8008;
    proxy_set_header Host $http_host;
    proxy_set_header      Upgrade $http_upgrade;
    grpc_read_timeout 300s;
    grpc_send_timeout 300s;
    grpc_pass grpc://localhost:5555;
}
location ~ ^/(ws|terminal/.+)$  {
    proxy_pass http://127.0.0.1:8008;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    proxy_set_header Host $http_host;
}
#PROXY-END/

/opt/nezha/dashboard/data/config.yaml 也添加了
proxygrpcport: 443
tls: true

cf上也开了grpc和云朵
