Hi, after the recent update of IP addresses, our app is no longer reachable when the prefix www. is included. I went through all the forum posts and consulted AI, yet was unable to resolve the issue. The app works fine when accessed via myadg.cz or [https://myadg.cz](https://myadg.cz) (where the app is published via Glide), yet it does not work when accessed from www.myadg.cz or [https://www.myadg.cz](https://www.myadg.cz). Before the IP update this was solved by a CNAME record pointing from www to the root domain. Now with the same setting it is not working anymore. Below are some screenshots of the browser screens. Thank you for any suggestions. ![When accessed from https://www.myadg.cz](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/d/8/d86e2b665a6b3bd9551fc2056ce6c037fb065703.png) ![When accessed from www.myadg.cz](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/d/2/d25b9cb555eaddf4ae7d90e674a8358577e77f86.jpeg) ---

Whats your current www redirect setting in DNS? ---

Yes, after the issue, I set everything anew. ---

So in my experience, `www` records typically point to a value on the application host or site host (usually a DNS address), not the primary domain as you have it listed here for the value. This would ensure your www traffic is redirected to the same location as your primary domain traffic. Not sure if it’s the particular interface you are using, but typically for “host” values you only use the `www` and not the full address (`www.myadg.cz`). ---

I set the CNAME up the same way as everybody did on the forum and it used to work fine before Glide changed the IP addresses. So you mean that the www CNAME should point to xxx.glide.page instead of myadg.cz? Thanks! ---

I would give that a shot and see how it resolves. Right now you are just doing a www redirect to your full domain. In my case I host a site and redirect www directly to the site host address so they get the same experience as someone browsing to the primary domain (also linked to the site host). ---

Tried this solution. Unfortunately no luck so far. ---
