Hi @sl811 can you provide the links and more information about the redirect and error you are receiving?

The hubspot domain is clunky. A saw it was possible to redirect and use a different domain name at my hosting provider.
I own the domain ProductiveLawOffice.com and pay for hosting at InMotion hosting.
I added a subdomain Enroll “enroll.productivelawoffice.com

I learned my hosted subdomain was not setup correctly. Thank you.
