Call timed out (error 1006) - bigbluebutton

Question

I have installed bigbluebutton on my serverand it was working properly but suddenly microphone can not connect anymore and after a while being stucked in "echo test" i'll get 1006 error and i have tested:

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.

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

but it doesn't solve the problem.

this is output of bbb-conf --check:

I tested everything i found and the problem still exists. is there any way? Thanks in advance.

Answer 1

run the command:

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

something like this will open:

    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;
}

change the (proxy_pass http://...) line to the following:

proxy_pass https://49.12.60.238:7443;
