PHP MVC项目Telegram机器人Webhook返回302 Found错误求助

我有一个基于PHP的MVC站点，接收Webhook响应时，Telegram返回错误信息：Wrong response from the webhook: 302 Found。

• 已通过https://api.telegram.org/botTOKEN/setwebhook?url=https://mysite-domain/webhook成功注册Webhook。
• SSL证书采用Let's Encrypt。

getWebhookInfo()方法执行结果

[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
      )

我认为问题出在.htaccess配置上。根目录下的.htaccess(1)将请求重定向到/public文件夹，而/public下的.htaccess(2)将请求转发到index.php。特此求助，感谢所有提供帮助的人。
