HELP: instagram link popup saying "be aware of potential scams" - why?

I NEED HELP: I have just changed the nameserver to Cloudflare from GoDaddy for a DIFFERENT domain but now my other domain is acting up so when I go on my Instagram account and click on the link, a popup shows up saying “be aware of potential scams” which never happened till now

What is going on ? Please help!!

This is something you need to contact Instagram over. They are the only ones who know why that popup would appear.
