4. Remember that you need to be within range of your watch's configured Wi-Fi access point to utilize this functionality. If supported by your device, LTE offers a longer range, but network charges may apply. 4.

5. On some Garmin devices, the HTTPS handshake is performed using **TLS 1.2**. If your server or proxy enforces a higher minimum (e.g., TLS 1.3), you will encounter an SSL handshake error with the message: `HTTP request returned error code = 0` 5. On some Garmin devices, the HTTPS handshake is performed using **TLS 1.2**. If your server or proxy enforces a higher minimum (e.g., TLS 1.3), you will encounter an SSL handshake error with the message:
To fix this, lower the minimum TLS setting to allow TLS 1.2. For example, if you are using **Cloudflare Tunneling**, go to: ```
`SSL/TLS → Edge Certificates → Minimum TLS Version` HTTP request returned error code = 0
and set it to **at most TLS 1.2**. _Reducing below TLS 1.2 is not recommended due to security risks._ ```
This limitation only affects **Wi-Fi/LTE connections**. When connected over **Bluetooth**, the watch routes requests through the paired phone, which handles the TLS handshake and supports newer TLS versions (such as 1.3) without issue.
