Nginx basic auth不能处理某些url

我已经配置了nginx基本身份验证。这对所有url都很好。现在,我添加了一个新的/jenkins(.*),但是身份验证不起作用。无论有无密码,我都无法访问/jenkins url。Nginx服务器配置:

    server {
            listen 8080;
            auth_basic "Restricted Content";
            auth_basic_user_file /etc/nginx/.htpasswd;

        location ~ ^/analysis/ {
                proxy_pass http://10.0.0.195:8070;
                proxy_set_header Host            $host;
                proxy_set_header X-Forwarded-For $remote_addr;
        }

        .
        .
        .
        .
        .
        .
        .

        location ~ ^/jenkins(.*) {
                proxy_pass http://10.0.0.21:8080;
                proxy_set_header Host            $host;
                proxy_set_header X-Forwarded-For $remote_addr;
        }

    }
