It worked, and then it stopped

Three causes explain almost every case, and they are worth checking in this order:

1. Your session expired. A configuration lasts 30 days. If it has been about that long, create a new configuration — sign in at litoravpn.com/get or open a fresh setup link. This is the most common cause and takes two minutes.
2. The network learned your tunnel type. Filters that block VPNs recognise the standard WireGuard handshake. If a standard tunnel stopped connecting and a new configuration did not help, create a disguised (AmneziaWG) configuration instead — that is exactly what it is for.
3. The exit address was blocked. Addresses that get blocked are retired and replaced on our side; a newly created configuration lands on a current address. Again: create a new configuration.

Notice the pattern: create a new configuration fixes all three. If a fresh disguised configuration still cannot connect, message the bot and say which network you are on (mobile or fixed, which operator) — that is the information that helps.
