Can someone please help with this error?

I haven't made any changes or updates to any dns records recently but today i tried to go to one of my webpages and i started getting this error. Not sure what it means or how to address it. Any help would definitely be appreciated. Note: Im using cloudflare in conjuction with HighLevel. my main domain is still active, its just the "www" subdomain that seems to be having issues. other subdoamins(go.mysite.com) still work. Just not my main www site. The help center says it prohibts cname records between different accounts but i dont ahve any other accounts
