+## Troubleshooting `SSLV3_ALERT_HANDSHAKE_FAILURE`
+
+A `SSLV3_ALERT_HANDSHAKE_FAILURE` error when connecting to the router indicates that there is a mismatch with the cipher being used in the SSL connection (see [here](https://stackoverflow.com/a/73254780/487356)).
+
+Running `openssl s_client -connect <router-ip>:<ssl-port>` on the router shows what cipher can be used. In the case of a "Sunrise Internet Box" it was `AES256-GCM-SHA384`.
+
+The following code snippet shows how to set up a `SagemcomClient` configured to use that specific cipher (and not validating the router's certificate):
+
+```
+async def main() -> None:
+    sslcontext = ssl._create_unverified_context()
+    sslcontext.set_ciphers("AES256-GCM-SHA384")
+
+    session = ClientSession(
+        headers={"User-Agent": f"{DEFAULT_USER_AGENT}"},
+        timeout=ClientTimeout(DEFAULT_TIMEOUT),
+        connector=TCPConnector(
+            ssl_context=sslcontext
+        )
+    )
+    async with SagemcomClient(HOST, USERNAME, PASSWORD, ENCRYPTION_METHOD, session=session) as client:
