BBB 2.3 couldn't make it work on a public address

[Idriss Hassani]

Hello everyone, I hope you are doing fine,

I know my problem is common but I really tried many leads from different websites but I couldn't solve it...

I'm working for a company and they put me on a project where I have to add BBB to Mattermost. 

Here is what I get with bbb-conf --check

for the SSL Certificates I have configured it correctly because when I tried it in our private network it worked perfectly.

I hope you can help me, I'd really appreciate it.

Kind regards
