I recently updated dns records to change our app domain from domain.com to app.domain.com. I previously had our landing page and app under domain.com but added a wix landing page to domain.com and changed our app to app.domain.com.
The records pointing to our wix site took effect within an hour, and everything is working fine. However, dns records pointing app.domain.com have still not propagated.
I understand it can take up to 72 hours to fully propagate, but in the past there has never taken more than a few hours.
Is there anything I may have missed, or am doing wrong? Any insight is greatly appreciated!
I don’t think you have the right IP addresses set for the subdomain. The ones in your screenshot are Cloudflare addresses themselves. They should be the address of your app server.
