401 Unauthorized /api/v1/collections/statistics when try to expose web interface from local network to internet

[fightingyuman]

Describe the bug:
I use nginx to proxy attu web interface in an internal network environment to internet, I get this error when click "Connect".

Steps to reproduce:

1. My host IP is 192.168.171.232, with milvus port 19530, insight port 3000. My docker started with HOST_URL=https://attu.mydomain.com:13679 and MILVUS_URL=192.168.171.232:19530
2. I installed nginx proxy for this host, expose port 13679 and use host name attu.mydomain.com with ssl on, and proxy it to 192.168.171.232:3000. here is my nginx conf:

server {
   listen       13679 ssl;
   server_name  attu.mydomain.com;
   root         /usr/share/nginx/html;
   ssl_certificate "/ssl/server.crt";
   ssl_certificate_key "/ssl/server.key";
   ssl_session_cache shared:SSL:1m;
   ssl_session_timeout  10m;
   ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
   ssl_prefer_server_ciphers on;
   location / {
           proxy_pass http://192.168.171.232:3000/;
           proxy_redirect default;
           add_header 'Access-Control-Allow-Origin' '*'; 
   }
}

3. I can access the website https://attu.mydomain.com:13679 on internet and connect milvus returns 200, but after connected, when access /api/v1/collections/statistics, it returns 401 Unauthorized. The attu server logs is here:

POST 200 /api/v1/milvus/connect 106.541 ms @ Mon, 27 Dec 2021 09:54:01 GMT ::ffff:192.168.171.232 from undefined Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.110 Safari/537.36 

GET /api/v1/collections/statistics 401 UnauthorizedError: Please connect milvus first

GET 401 /api/v1/collections/statistics 3.464 ms @ Mon, 27 Dec 2021 09:54:01 GMT ::ffff:192.168.171.232 from undefined Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.110 Safari/537.36

The web browser POST to https://attu.mydomain.com:13679/api/v1/milvus/connect post data is:

{"address":"192.168.171.232:19530"}

and the server returns data is:

{"data":{"address":"192.168.171.232:19530"},"statusCode":200}

Fine way:
I can access it when in the local internet. change HOST_URL to http://192.168.171.232:3000, then everything is fine.

Attu version:
zilliz/attu:latest

Milvus version:
milvusdb/milvus:v2.0.0-rc8-20211104-d1f4106

We fixed 401 error and update docker 6 days ago. May be your zilliz/attu is not the newest.

Please try to remove your zilliz/attu local and pull it again.

It's the newest version. here is my RepoDigests, it match digest on docker hub:

[root@localhost home]# docker inspect zilliz/attu:latest 
[
    {
        "Id": "sha256:b5d0c4ba815dc1c34ef9cbb1d747093b63b6ce0c56f31962643e567222e46516",
        "RepoTags": [
            "zilliz/attu:latest"
        ],
        "RepoDigests": [
            "zilliz/attu@sha256:489ef0eb4e72762f6021ab7d1cfe92a597bbde4e85e9d0ebfbd3c97b73a89039"
        ],

When I use the IP address 192.168.171.232, It's good.
But when I use nginx proxy, and set Host url to the domain url, it expose 401 Error.

@fightingyuman We set milvus_address header when call attu server.
If use nginx to proxy server, nginx will ignore underscores headers.
Already fix it , will release it. today, please try it again.
Thanks you and sorry for reply delay :)
