I have managed to set up a WebRTC Wowza app. Generated a self signed cert, added all the configs according to the docs. I have set up Wowza on a standalone server to be able to test it remotely. However when I try to publish I quickly get disconnected. Console output: ```auto gotDescription: {"sdp":{"type":"offer","sdp":"v=0\r\no=- 3359413190172768985 2 IN IP4 127.0.0.1\r\ns=-\r\nt=0 0\r\na=group:BUNDLE audio video\r\na=msid-semantic: WMS

Hello @Sebastiaan Peek What browser are you testing your WebRTC “publish” with? If using Firefox, I would recommend version 51.0+ I would also recommend having the below ports open in your Firewall and port forward if going across networks. TCP: 1935, 443, 9443 (if using Wowza Sample Web Server) UDP: 6970-9999 and sometime up to 65535 If that does not help, please open a case [here](https://www.wowza.com/support/open-ticket) with the below info: **[install-dir]/conf** **[install-dir]/logs (only latest logs showing a server reboot and connection attempts is needed)** **[install-dir]/htdocs (if using)** **Browser versions used.** If you are not sure how to get this information please see the following tutorial.[https://www.wowza.com/docs/how-to-create-a-compressed-zip-file-in-windows-os-x-and-linux](https://www.wowza.com/docs/how-to-create-a-compressed-zip-file-in-windows-os-x-and-linux) Regards, Jason ---

Better open all udp ports
