Web Conference Unable to connect to server

  • T

    I am on MDaemon 25.5.1 hosted on Windows 2019 Standard. I am unable to use the Web Conference feature. When I login to Webmail I get a small temporary pop-up that says "Web Conference Unable To Connect To Server" I have the Conference feature enabled, to the best of my knowledge, everywere it should be. I have a valid certificate issued from a trusted third party authority. Below is my RTC-ServerMain.log

    I see two issues.

    1. You need to add the local and/or public IP addresses of the MDaemon server as STUN server IP addresses.  You can do this by logging into Remote Administration as a Global Admin and going to Main | Web Conferencing Server.

    2. The export of the MDaemon certificate is failing, this is probably because its marked as not exportable in the Windows Certificate Manager.  You'll need to either re-import the certificate into the Windows Certificate store as exportable or place a privatekey.pem and publickey.pem files in the C:\MDaemon\PEM\_rtcserver directory, and restart RTCServer.

    That was it. Thank you. The confusion came from the .pem files not being in the C:\MDaemon\PEM\_rtcserver directory. Our certificates are not typically stored in the Windows Certificate Store as exportable. I really appreciate the help.
