Shouldn’t have to, no, but you might need to redeploy your site after changing its URL since some internal proxying we do to enable identity/git gateway may need to be refreshed in a way that only happens at deploy time. If that doesn’t help, we would need to know your actual site to take a look and help out. You could give us your site’s API ID from the general settings page if you don’t want to mention the URL here, but that also prevents anyone not on our staff from advising you so keep that in mind based on your urgency level
