+# Server Errors
+
+## Address already in use: bind
+This error is derived from the server being unable to bind to a certain port.
+The server uses ports: `8888`, `443`, `80`, and `22102` (by default)
+
+**Potential places for error**:
+- The dispatch (web/HTTP[S]) server has double-bounded.
+- One of the above ports (or any you've specified) has been bound to by another process.
+
+**Solutions**:
+- If an SSL certificate error is logged to the console, check your `keystore.p12` is in the correct place and with the correct password.
+- Run `netstat -aon | find /i "listening"` to find processes with the server ports. Then kill the process with `taskkill /PID <PID>`.
+
+# Client Errors
+
+## Code 4206
+This error is derived from the client not being able to properly query the current server region.
+
+**Potential places for error**:
+- The client cannot properly establish an encrypted connection to the local server.
+- The server is not properly handling the `query_cur_region` request.
+- Your proxy isn't setup properly and isn't redirecting the `query_cur_region` request.
+
+**Solutions**:
+- Add the `keystore.p12` certificate to your system's **trusted certificate root authority** list.
+- Double-check you can access `https://127.0.0.1/query_cur_region` in the browser.
+- Check the settings for the proxy you are using (ex. Fiddler with its Fiddlerscript, MiTMProxy with its Python script, etc.)
