BBB Unable to connect to default URL for or a BigBlueButton server

Hi All,

I have just installed BigBlueButtonBN plugin version  2.3.1, on Moodle 3.8.1+ (Build: 20200124), and it is with the default configuration (default URL and default salt).
When I go to the courses and try to add BigBlueButtonBN as an activity or resource I got this error:

"Unable to connect. Please check the url of the BigBlueButton server AND check to see if the BigBlueButton server is running."

The Moodle server can communicate with the BigBlueButton server
When I am running ```wget -qO- http://test-install.blindsidenetworks.com/bigbluebutton/api```
I am getting the correct response

My moodle serevee spec 
OS: CentOS 8.0.1905
Server version: Apache/2.4.37 
PHP 7.3.13

Any help?

Regards
Risto

I find the solution.

The problem was with Selinux, so one option was to disable it, and another one was to add extra permission.

Selinux is a kernel security module for Linux that implements ACL. Something like a firewall, so if outgoing requests are bloqued, Moodle won;t be able to access BBB. If inbound requests are blocked, BBB won't be able to send notifications when recordings are ready or pull the pre-uploaded presentation.

So, for a full implementation, both servers have to be able to talk to each other.

Cheers,

so there were two solutions to my problem:
1. The more easy one just disable the SELinux
Open the /etc/selinux/config file and set the SELINUX mod to disabled

2. update the SELinux policy to allow HTTP scripts and modules to initiate a connection to a network or remote port.
