nginx反向代理出现问题

[xfhmbjs_]

#user nginx;
worker_processes 1;

error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;


events {
worker_connections 1024;
}


http {
include /etc/nginx/mime.types;
default_type application/octet-stream;

log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';

access_log /var/log/nginx/access.log main;

sendfile on;
#tcp_nopush on;

keepalive_timeout 65;

#gzip on;

include /etc/nginx/conf.d/*.conf;

server {
listen 8800;
server_name 221.211.9.41;
client_max_body_size 1024M;

location /rs-manage-sys {

proxy_pass http://10.21.1.98:8080/rs-manage-sys;
# proxy_set_header Host $host:$server_port;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
以上是我的nginx配置

直接访问221.211.9.41：8800 是可以nginx欢迎页面的，但是访问221.211.9.41：8800/rs-manage-sys 进行反向代理的时候 却显示访问的页面出错了 是404 也就是找不到http://10.21.1.98:8080/rs-manage-sys这个项目地址
查找日志显示：

location /rs-manage-sys/ proxy_pass http://10.21.1.98:8080/rs-manage-sys/; 分别加个斜杠试试，看哪个起作用
