Not in the forums we can’t unfortunately. Requires a full review of your files and logs in a support ticket.

Take a look at this article for troubleshooting issues connecting to the service as well as related FAQ pages.

**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).

and also:  
Check that you have the required version of Java installed.

- Wowza Streaming Engine version 4.7.8 and later requires OpenJDK Java SE JRE 9.0.4 at a minimum but supports up to Java version 12
- If you are updating to 4.7.8 or later, you must have Java SDK version 9 installed before running the updater.
- For Java versions 9- 12, you must [point Wowza Streaming Engine](https://www.wowza.com/docs/manually-install-and-troubleshoot-java-on-wowza-streaming-engine) to the version you are using.
