Restart Bot
The button works automatically: it will turn ON if the bot was OFF, will restart the bot if it was ON.
Apply if your bot stops responding. This happens mostly if you tried to access it over the Web and lost the Webhook. Sometimes Telegram loses it by itself, but usually it's you.
❖ Error messages
❌ Bot start failed.
Telegram rejected the start of the bot. A VERY rare case, but it happens. Usually goes away within 1-2 hours. JUST WAIT. Writing in support of the constructor is USELESS - in this case, we have nothing to help you with.
