Inbound parse webhook url does not work

[devpro9219]

I've made the webhook URL to parse incoming email on localhost(Laravel project), and it works (it leaves some logs in the local file) after I register this URL(used the ngrok) in SendGrid inbound parse when sending email to registered domain email address. But after upload this project into the host(Siteground), and replace the inbound webhook URL with this host URL in SendGrid, it doesn't work (it doesn't write any logs in the local file). I've tested this live URL using curl post and postman, and this URL works well. I don't know why the SendGrid couldn't call this live URL when receiving the incoming email. Thank you.
