Excuse me, but I don't understand your response. Why aren't private messages being answered? I don't quite understand about the reward. Can you continue the conversation in the private thread?

I always used the Railway application settings, but since yesterday I haven't been able to get it to work as it always has. It gets stuck on the message: "Waiting for DNS update..." and the custom domain isn't working; the application says: "ERR_CERT_COMMON_NAME_INVALID". It never delivers the updated DNS; it's been like this for over 20 hours. Note: Regions & Replicas US East (virginia, USA)

I already tried deleting the custom domain and recreating it, I also deleted the CNAME and recreated everything, but it always gets stuck on: "Waiting for DNS update..."

I've never added anything else to the settings; I've always done it using the CNAME record for the main domain. In the hosting CNAME manager, I enter the address that Railway provides and then wait for the DNS to propagate. I've never used TXT files; can you explain more about TXT files?

Where is it added? And what is added?

And who does the railway pay for it?

The problem was solved using information from: https://station.railway.com/questions/custom-domain-txt-file-not-being-recogni-a1b2633c

I have no idea what a reward is; I've never used it before and I'm new to this. I just posted the answer that helped me solve the problem after many hours of research and searching for information.
