Hi,
We want to use our servers BigBlueButton using Let’s Encrypt Certificates (https://github.com/bigbluebutton/bbb-install)
We get an error on Let’s Encrypt. We gave permissions on 80 And 443 Ports. But Our server was accessible only from Turkey IP addresses. I send screenshot. How to fix it?
Timeout during connect (likely firewall problem)
To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address. Additionally, please check that
your computer has a publicly routable IP address and that no
firewalls are preventing the server from communicating with the
client. If you’re using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.
