# System check

The System check is a diagnostic page designed to ensure that your setup is correctly configured for optimal performance when using our platform. It verifies key components of your environment, including your browser, network connections, and server accessibility. By running the System Check, you can identify and resolve any potential issues before joining or hosting a session.

Note:\
Added a German translation for the System Check page. This enhancement is activated when moderators select "German" as the default language under Default Room Settings. German-speaking users can now navigate and understand the system check process more easily.

\
The System Check performs the following tests

1. **Browser Compatibility Check**

   Ensures you are using a supported browser (e.g., Google Chrome) for the best experience.
2. **Signalling Server Connectivity**

   Confirms that your network can successfully connect to our signalling servers, which handle session initiation and real-time communications.
3. **Media Server API Check**

   Tests the connection to our media servers, ensuring audio, video, and screen-sharing functionalities will work seamlessly.\ <br>

Even if your test was successful, please take note of the following details to ensure stable media connectivity. You can check specific connection details in your dashboard under **System check** after logging in:

* **Option 1**: Allow direct client connections to media servers via RTP on TCP/UDP ports 20000–40000
* **Option 2**: Use TURN relay over UDP via port 3478
* **Option 3**: Use TURN relay over TCP/TLS via ports 5349 or 443
