When I use sub path for the focalboard such as http://192.168.7.43/focalboard, login and register new account not work it display login failed error for login and undefined for register new account .

My conf.json is: { "serverRoot": "http://192.168.7.43/focalboard", "port": 8000, "dbtype": "postgres", "dbconfig": "postgres://focaluser:password@localhost/focaldb?sslmode=disable&connect_timeout=10", "postgres_dbconfig": "dbname=focalboard sslmode=disable", "useSSL": false, "webpath": "./pack", "filespath": "./files", "telemetry": true, "prometheusaddress": ":9092", "session_expire_time": 2592000, "session_refresh_time": 18000, "localOnly": false, "enableLocalMode": true, "localModeSocketLocation": "/var/tmp/focalboard_local.socket" }

my nginx.conf is:

upstream focalboard { server localhost:8000; keepalive 32; } server { listen 80; listen [::]:80;

server_name 192.168.7.43;

location /focalboard { proxy_pass http://127.0.0.1:8000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }

location /mattermost {
    proxy_pass http://127.0.0.1:8065;
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

}
