Hi there,

It might be that the certificate used for SSL isn't recognized by Java, which will cause the API calls to fail.  On the server, try the following


and see if you get an error.

Regards,... Fred

and let us know what you see.

Hi,

> It said "Invalid host name."

This is likely the source of your problem.  Check the DNS setting on your server, and try do do a simple ping such as

 ping google.com

If you don't get a response, try updating the DNS settings with Google DNS

The 404 response in the first post is very strange.


HTTP Status 404 - /bigbluebuttonhttps:/www.midtsandbox.com


type Status report

message /bigbluebuttonhttps:/www.midtsandbox.com

description The requested resource is not available.

That isn't a valid URL and is a reasonable 404. It looks like you've got a typo somewhere in one of the config files because it looks like it might be trying to redirect to "https:/www.midtsandbox.com" which isn't a valid URL as there's only one '/'.

I search all the configure file, there is no https:/midtsandbox.com (only one /), all are https://

You can use Mconf's API Mate tool to test the individual API calls http://mconf.github.io/api-mate/. If you plug in your server name and shared secret (bbb-conf --salt) you can run the individual calls. Run create first and check the output.

Hi there,

> How did you fix it?

We need more information to narrow down the issue

1. What version of BigBlueButton are you installing/running?
2. Did you get any errors during the install?
3. What installation method did you follow?
4. Did the problem appear after initial install, after an upgrade, or after running BigBlueButton for a while?
5. Did you make any changes to BigBlueButton outside of using bbb-conf or the bbb-install.sh script?
  - If you setup your own certificate, can you check it with SSL labs http://docs.bigbluebutton.org/2.2/install.html#test-your-https-configuration
6. Are you running BigBlueButton within a development environment?
7. Post the output of sudo bbb-conf --check

Regards,... Fred

Hi Fred,
The server was working before the ssl certificate installed. Now, I'm facing an error while joining classroom after on the link https://tipsalon.mku.edu.tr/demo/demo1.jsp 

I used this command to install, last time:  wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v xenial-220 -a 

Best wishes...
Tacettin

Can you check the URL in bigbluebutton.properties for the value of bigbluebutton.web.serverURL.  Does it have https?

Looks like there's multiple issues with the configuration. I'm only getting a "B" rating when I test your SSL configuration on this site (https://www.ssllabs.com/ssltest/analyze.html?d=tipsalon.mku.edu.tr&hideResults=on). You should be getting an "A". The incomplete certificate chain will almost definitely cause issues.

Beyond the certificate issues, you need to go through all of our documentation on setting up SSL to make sure you change all of the places that need it http://docs.bigbluebutton.org/2.2/install.html#configure-ssl-on-your-bigbluebutton-server
