Why facebook does not allow my shortened url to post

I am posting a shortened URL (https://tick.ws/vcmme7e) in a Facebook post, and it's giving an error

"Your post couldn't be shared, because this link goes against our Community Standards"

I tried to directly post the link (https://contentproz.com/our-process.aspx) without URL shortener and its working fine, also I have tried other URL shorteners like bitly and tiny URL they are also working. Currently, I am using tickws.com to shorten my link, that's our company's web app and we have to shorten the link through this website.
