If you are facing an issue with Kurento Media Server, follow this basic check list:
Step 1: Test with the latest version of Kurento Media Server. We do not provide support for older versions. Follow the installation instructions here: Installation Guide. You can also try with a nightly build, to see if the issue has been fixed in the latest (unreleased) development branch: Installing Nightly Builds.
Kurento does not provide free personal support. We do offer professional consulting, which you can request by writing an email to openvidu[AT]gmail.com.
For more information about reporting bugs, where to get support, and commercial enquiries, have a look at the Support page in the Kurento documentation.
