SOLVED You are seeing this page because this domain points to Cloudron server IP but no app is installed on that domain.

This shows up when typing in www.domain.com (domain.com without 'www' loads the app just fine, however)

CNAME is set correctly.. Using cloudflare and global API token... have renewed certs and resynced DNS, no idea how to remedy this.

@jordanurbs just a CNAME is not enough. You need to tell Cloudron which app is www subdomain. You can do this by adding www location in the Location section of the app. I guess it's a Redirect - https://docs.cloudron.io/apps/#redirections ?

@girish Thanks, that seems to have taken care of it
