Call timed out (Error 1006)

[Andrew Barrett]

Hi, I have tried to follow the solutions found in the documentation and other tickets for error 1006 but have had no luck. The issue occurred after migrating the existing server from Ubuntu 16 to 18 on AWS. Below is the output of the bbb-conf --status and bbb-conf --check, and I have attached the output of bbb-conf --debug. Thanks for any help.

The problem was solved be re-running the bbb-install script:

wget -qO- http://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v bionic-23 -s our.domain.com -e in...@our.domain.com

The only thing that I notice the script has corrected was in:

/etc/bigbluebutton/nginx/sip.nginx

It changed it from https to http and from port 7443 to 5066.

This was contrary to what other tickets on the internet were suggesting to fix the issue (they were suggesting to use https with port 7443).

I am certain that under Ubuntu 16 it was configured with https and port 7443.

As it turns out, under https://docs.bigbluebutton.org/2.2/install.html#configure-freeswitch-for-using-ssl

there is a section beginning with:

"Note: As of BigBlueButton 2.2.29 (and later), you can have nginx proxy incoming WSS connections to WS on port 5066 to work around a bug in FreeSWITCH."

The script that it provides there would have fixed my issue (as it makes the change I mention above).
