调用超时（错误 1006）- bigbluebutton

Question

我在我的服务器上安装了 bigbluebutton，它工作正常，但麦克风突然无法连接，一段时间后卡在“回声测试”中，我会收到 1006 错误，我已经测试过：

FreeSWITCH fails to bind to IPV4Anchor link for: freeswitch fails to bind to ipv4

In rare occasions after shutdown/restart, the FreeSWITCH database can get corrupted. This will cause FreeSWITCH to have problems binding to IPV4 address (you may see error 1006 when users try to connect).

To check, look in /opt/freeswitch/var/log/freeswitch/freeswitch.log for errors related to loading the database.

2018-10-25 11:05:11.444727 [ERR] switch_core_db.c:108 SQL ERR [unsupported file format]
2018-10-25 11:05:11.444737 [ERR] switch_core_db.c:223 SQL ERR [unsupported file format]

2018-10-25 11:05:11.444772 [CRIT] sofia.c:3049 Cannot Open SQL Database [external]!

If you see these errors, clear the FreeSWITCH database (BigBlueButton doesn’t use the database and FreeSWITCH will recreate it on startup).

$ sudo systemctl stop freeswitch
$ rm -rf /opt/freeswitch/var/lib/freeswitch/db/*
$ sudo systemctl start freeswitch

但是并没有解决问题

这是 bbb-conf --check 的输出：

我测试了我发现的所有内容，但问题仍然存在。有什么办法吗？提前致谢。

Answer 1

运行命令：

sudo nano /etc/bigbluebutton/nginx/sip.nginx

这样的东西会打开：

    location /ws {
        proxy_pass http://49.12.60.238:4066;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_read_timeout 6h;
        proxy_send_timeout 6h;
        client_body_timeout 6h;
        send_timeout 6h;
}

将 (proxy_pass http://...) 行更改为以下内容：

proxy_pass https://49.12.60.238:7443;

Answer 2

请注意，我关注了 https://github.com/bigbluebutton/bigbluebutton/issues/2628 上的帖子，但直到我运行执行以下命令后问题才得以解决：

$ wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v xenial-22 -s myserver.com -c turn.myserver.com:1004a200000000004cb3f2d6f000d85d -e johndoe@myserver.com -d -g | tee bbb-install.log
