Invalid webhook response (302 Found) from Telegram bot in PHP (MVC)

Question

Good day! I have an MVC site in PHP. The essence of the problem is that when receiving a webhook response, Telegram sends an error message - Wrong response from the webhook: 302 Found.

• The webhook was successfully registered using the link https://api.telegram.org/botTOKEN/setwebhook?url=https://mysite-domain/webhook.
• SSL: certificate Let's Encrypt.

Result of getWebhookInfo() method

    [ok] => 1
    [result] => Array
          (
                    [url] => https://mysite-domain/webhook
                    [has_custom_certificate] => 
                    [pending_update_count] => 8
                    [last_error_date] => 1658579570
                    [last_error_message] => Wrong response from the webhook: 302 Found
                    [max_connections] => 40
                    [ip_address] => x.x.x.x
          )

I think the problem is in .htaccess. The root folder has .htaccess (1) and requests are redirected to the /public folder. And in .htaccess(2), requests are sent to index.php. Learning. Thanks in advance to all those who help in solving this problem.

.htaccess (1):

    RewriteEngine On
    RewriteRule (.*) public/$1

.htaccess (2):

    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d

    RewriteRule (.*) index.php?$1 [L,QSA]
