I connected my domain and publish my site but I got this error so I have connected a domain on Hubspot, so do I need to get hosting now?
Hi @CDiwakar,

I would recommend clearing your cache first to see if this resolves the error.
I’ve included a couple of step-by-step articles below from Google below for you.
