This article highlights common configuration mistakes during single-server installations. These are small steps that may have been missed in a basic install. If you are looking for more in-depth troubleshooting guides, including guides for special features like Autoscaling, please see our full Troubleshooting Guide FAQ.
To avoid small mistakes during single-server installs, please make sure that you have done the following:
Ports
Open all required ports.
Version
Run the latest version of the server and/or SDKs (it may have a fix for the issue you are seeing!)
Memory
Make sure you have allocated enough memory to the JVM.
Network (for local testing)
If you are running Red5 Pro locally, all your devices need to be on the same network.
License
If you have a custom build or preview build of the Red5 Pro server, check that your License Key is present in the server. This only applies to custom or preview build scenarios. When downloading the server from the Accounts page, your license key should already be entered.
- Follow the instructions here if your server build arrangement requires it: How do I install my Red5 Pro License?
