GO web程式代理繫結域名非常頻繁404的問題

用 nginx 做代理 配置檔案如下：<div><br></div><div><pre><code>server { listen 80; server_name leechan.online; location / { proxy_pass http://127.0.0.1:8888; proxy_http_version 1.1; #proxy_cache_bypass $http_upgrade; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Port $server_port; } access_log /home/wwwlogs/leechan.online.access.log; } </code></pre><p><br></p></div><div>但是經常出現 404 的情況，是非常頻繁出現。 IP 訪問：http://117.50.7.147:8888 域名訪問：http://leechan.online

各位大佬能指教一下是什麼問題嗎 <p><br></p></div>
