Common Error Experienced
Wowza Streaming Engine Manager could not connect to the Wowza Streaming Engine service (http://localhost:8087). Verify that the Wowza Streaming Engine service has started and is running.
Note!
By default, Wowza Streaming Engine server software and Streaming Engine Manager install as system services and both should start automatically when you start your computer.
Troubleshooting:
1. Confirm that Wowza Streaming Engine is running:
- Open a web browser and enter the URL:
http://[wowza-ip-address]:1935/ServerVersion
([wowza-ip-address] is the IP address or domain of the Wowza Streaming Engine server.) - If Wowza Streaming Engine installed correctly, the browser displays the Wowza Streaming Engine version number.
- If not, make sure that the server is running and that TCP port 1935 is open on your router, firewall, and/or software firewall (iptables on Linux).
2. Make sure that you have the appropriate ports open to access the Wowza Streaming Engine and Wowza Streaming Engine Manager services, and that HTTP requests are being routed correctly through these ports.
3. Verify that Wowza Streaming Engine services are listening on the ports that you have specified.
Check listening ports on Windows
-
Open Command Prompt and run the command:
netstat -an | findstr "1935 8088"
You should see output similar to the following:
TCP 0.0.0.0:1935 0.0.0.0:0 LISTENING
TCP 0.0.0.0:8088 0.0.0.0:0 LISTENING
Check listening ports on macOS and Linux
-
Open Terminal and enter the command:
netstat -an | grep '1935|8088'
You should see output similar to the following:
tcp 0 0 0.0.0.0:1935 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:8088 0.0.0.0:* LISTEN - If the appropriate ports aren't open, check your server's firewall configuration to make sure it isn't blocking them. Please review the port configuration instructions here.
- After opening ports, you must stop and restart Wowza Streaming Engine and Wowza Streaming Engine Manager. Please review how to start and stop Engine instructions here.
3. If you are using a proxy server to have the server connect to the internet:
- You must add server properties to Wowza Streaming Engine media server software so that it uses a proxy server to communicate with the Wowza licensing server.
- Please review the steps to configure a proxy server here.
4. If nothing above has fixed the issue, then you may have an issue with your license key.
- You should review your current wowzastreamingengine_access.log to see if you have any license-related errors in your start-up sequence. See the related license troubleshooting articles below.
