Error - Site under maintenance

Dear Sir,

I just discover that there is an error message on our website

"# Site under maintenance is currently under maintenance. We should be back shortly. Thank you for your patience."

I don’t understand what is the problem.
I did the updates for Drupal 9 with one of your colleagues and he said it would be ok.
Now, I don’t know what to do, could you please help me?

Best regards,

Right now I’m taking care of it for you.
