Telegram bot work

[ToadMr]

Hello!
Please help me figure out the problem, why the bot in Telegram does not work correctly?
Description:
Installed Marzban.
Configured Marzban config for Telegram, as specified in the documentation.
Notifications come to Telegram (subscription created, successful/unsuccessful login), but I cannot control the bot.
There are buttons for control, I created a default template for creating a subscription, configured it according to the instructions. The point is that I can't even get information about the system from the bot.

Tell me how to overcome this?
What data do I need to provide you?

/start
Provide more information, maybe a screenshot

When I press any button, even "System Info", the button blinks for a while, but nothing happens

What's interesting is that if I enter a command, for example
/user test
Just "test" is the login of a real user, then I get information about the user.

After reinstalling the system, the bot started working. Thank you!
