If LINE says your bot stopped reporting, or the status shows Disconnected, check these 3 things in order. It's usually the first.
Step 1: Is the VPS still on?
Connect to the VPS with Remote Desktop. If you can't get in, contact your VPS provider.
If the VPS has just restarted, MT5 doesn't reopen by itself. Open MT5 again.
Step 2: Is MT5 open and logged in?
Look at the bottom-right corner of MT5. If it says No connection or Invalid account, log in again and check the Server.
Step 3: Is AutoTrading green?
If it's red, click it once so it turns green, and check the top-right of the chart to see the EA is still attached.
The gold market is closed on Saturday and Sunday. A bot not reporting then is normal.
Checked all three and it's still not back? Send your MT5 account number and a screenshot of the Experts tab to our admin.
