What are the steps to reproduce the issue?

I have been using Cloudflare tunnel (name: results) to access a website hosted on Synology NAS Webstation. Now trying to set up on Proxmox LXC container, which works fine when accessed locally from the LAN. I followed instructions and got tunnel working (name: results-ct), but when I try to connect via https I get the Error 1016 Origin DNS Error. I have looked through the Cloudflare troubleshooting but it didn’t help. I checked the settings against those for the existing website and tunnel, but I can’t figure out what is causing the error. I feel like I must be missing something obvious, but I’m just not seeing it. Does anyone have suggestions on what to check or potential solutions?

UPDATE: Now working. I noticed that the Content for the “results” CNAME was not just the tunnel id, but had “.cfargotunnel.com” tacked onto the end. I added that to the end of the tunnel id for “results-ct” and it worked.

Hopefully this helps someone else!
