this happens only while joining the meeting not for creating or anything else

What was the redirect rule that you wrote? If you're using the demos you should be able to set https in /var/lib/tomcat7/webapps/demo/bbb_api_conf.jsp.

Hi Krishna,

Are you setting up a new BigBlueButton server?  If so, can you try setting it up with the install script at

  https://github.com/bigbluebutton/bbb-install

which can automate the configuration of your server for HTTPS.  Try the above and let us know if it gets you going.

Regards,... Fred

Hi 

> I am new to bigbluebutton when i write redirection rule for http to https it throws java null pointer error.

If you are setting up a BigBlueButton server to use HTTPS, see

  http://docs.bigbluebutton.org/install/install.html#configuring-ssl-on-your-bigbluebutton-server

It sounds like you are trying to write a redirection rule in nginx.  To support both HTTP and HTTPS, you need only have the following

  listen 80;

  listen [::]:80;

  listen 443 ssl;

  listen [::]:443 ssl;

We did some googling for forcing a redirect in nginx from HTTPS to HTTPS and found this article

  https://www.digitalocean.com/community/questions/nginx-redirect-to-https

Krishna, 

you have incomplete chain in certs, causing this issue.

https://www.ssllabs.com/ssltest/analyze.html?d=anhance.org&latest

need to append the intermediate bundle to crt and restart nginx.

tomcat doesn't like that.

regards.

Stephen

You can also try setting up the server with the bbb-install.sh script, see

 https://github.com/bigbluebutton/bbb-install

which will setup a certificate for you using Let's Encrypt.  See

  https://github.com/bigbluebutton/bbb-install#usage
