DNS configuration issues for my test environment** **2. Some inners pages showing an error in production when they work fine locally** **FIRST ISSUE: DNS configuration issues for my test environment**   I have configured 3 domains for my project (see screenshot). * evocoach.fr - this points to my master branch, which is the production environment * www.evocoach.fr - this redirects to evocoach.fr * test.evocoach.fr - this points to my develop branch, which is the testing environment The first two work fine and I can see my website after pushing it to master. The issue comes with the last one, I am seeing an error in my configuration saying that the CNAME cannot be detected and I have an invalid configuration. I have tried the following steps: * Added the CNAME directly to my third party hosting provider - this didn't work * Changed the nameservers to Vercel nameservers and added the CNAME in vercel directly - this didn't work either. Note: with both configurations the master branch and domain work fine. Can you I have some assistance here? **SECOND ISSUE: Some inners pages showing an error in production when they work fine locally**  This one is straightforward, I have some inner pages that are showing a 404 error in production when others work fine. Example of 404 pages: * https://evocoach.fr/cguv * https://evocoach.fr/politique-de-confidentialite Example of page working fine: * https://evocoach.fr/contact Can I please understand why these pages are showing 404 while they are building and working fine locally? Thanks for the help! Amy Egan (@amyegan) · 2024-08-08 Hi @evodreamfr. The `*` CNAME record should cover all subdomains when you're using Vercel nameservers. Try removing the `test` CNAME and let me know if that gets it working for you. The 404 is a bit trickier since there are a lot of different reasons that a file may be at a different location or missing from a deployment entirely. This post has tips to help you locate the source of the problem: https://community.vercel.com/t/debugging-404-errors/437/1 Evodreamfr (@evodreamfr) · 2024-08-08 Hi @amyegan, thank you for the quick response! I forgot to mention in my post that we also try not having `test` and just left the `*` CNAME record but it wasn't working. I just removed it again, but it doesn't seem to be changing anything. Thanks for sharing the debugging link, I'll take a look. Amy Egan (@amyegan) · 2024-08-08 :sweat_smile: I just noticed the project domain settings screenshot shows `test.evodream.fr` rather than `test.evocoach.fr`. Does it work if you change the domain to `test.evocoach.fr`? Evodreamfr (@evodreamfr) · 2024-08-08 · ♥ 1 Ohh great catch! I totally missed it :sweat_smile: Thanks! Still viewing the 404 docs, will report here what I find. Evodreamfr (@evodreamfr) · 2024-08-09 · ♥ 1 Hi @amyegan, just a quick note that I could make these pages work by creating a vercel.json config file and adding the following snippet I found online. ``` { "rewrites": [ {"source": "/(.*)", "destination": "/"} ] } ``` Thanks for the help again!
