When we are trying to add our website URLs https://taiwan.kisan.app and https://taiwan.kisan.in in the Facebook advertisement.
We are getting the following error.
Invalid link URL Provided: The link URL https://taiwan.kisan.app used in the Ad is invalid. Please use a different URL and try again. (#2490193)
We are not able to understand what is causing this error as our site has SSL and it can be browsed from the browser without error.
The site is hosted on Apache, AWS EC2 instance and there is a load balancer before EC2.
How can we fix this?
