In order to send out your video stream, you will need to make sure there isn’t a firewall on your network blocking any ports. There are three ports that you want to focus on: 1935, 80, and 443.
Port 1935 – If you are streaming to Twitch or any private CDNs such as Livestream, UStream, Wowza, DaCast, and others, then you will need Port 1935 to be open.
Port 80 – If you are streaming to YouTube or Facebook, then you will need Port 80 to be open.Port 80 is the same port as is used to surf the web (aka http://).
Port 443 –Another port to be aware of and to check is Port 443. It is used to securely surf the web, do banking(aka https://) as well as to securely transmit other kinds of data, including streaming video and related information.
There are many free port checking tools available online, but our favorite is this one from TheRealTimeWeb. When you click the link – and press the test button – you should get “success” on the ports you need. Frequently Port 1935is closed – and that can be a show stopper. Don’t blindly trust what you’re told, docheck for yourself. (if you’re remote – always ask the onsite folks to send a screenshot showing “SUCCESS.”)
