思源笔记出现 blocked content， 卡在启动页面

今天是突然间出现如下的问题，前段时间运行的挺好，也没有做什么变更。帮忙看一下如何解决。

pdf.js 的网址出现了:6806；

启动代码：

docker run --name siyuan -it -d --restart=always -v /root/SiYuan:/home/siyuan/Documents/SiYuan -p 127.0.0.1:6806:6806 b3log/siyuan --ssl=true

nginx 配置：

   server {
        listen 443 ssl;
	client_max_body_size 100M;
 #       ssl on;
        ssl_certificate /root/ssl/siyuan.crt;
        ssl_certificate_key /root/ssl/siyuan.key;
        server_name www.siyuanvpn.com;  #随便写的域名，真实的不是这个
		auth_basic "My Server";
		auth_basic_user_file /etc/nginx/passwd; 
	location / {
	    proxy_pass http://127.0.0.1:6806/;
	    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;
	    proxy_set_header X-Forwarded-Proto $scheme;
	    proxy_http_version 1.1;
	    proxy_set_header Upgrade $http_upgrade;
	    proxy_set_header Connection "upgrade";
	    proxy_redirect off;
	  }
