What is the issue you’re encountering
the first cname (pointing to cfargotunnel’s uuid cname) does not work (returns 404 not found)
What steps have you taken to resolve the issue?
I tried to point that first cname directly to cfargotunnel’s uuid cname but that didn’t work
What feature, service or problem is this related to?
DNS records
What are the steps to reproduce the issue?
Thru Zero Trust/Networks/Tunnels panel, I set up a tunnel as A-DEV-SERVER enervisionmedia com
- THIS WORKS: can access site (hitting my local dev machine) thru browsers using A-DEV-SERVER’s URL
THEN, set up a CNAME record of PUBLIC enervisionmedia com that points to A-DEV-SERVER URL:
- this DOES NOT WORK
- although I can access the origin server directly if I use the tunnel’s explicit A-DEV-SERVER’s URL, when I try with PUBLIC as url I get back a 404/not-found error (AND I can see from logs it doesn’t even hit our local origin server).
I also tried to set the PUBLIC’s CNAME record to directly point to the tunnel’s CNAME name (namely its cfargotunnel’s uuid name) but got the same result back (404).
It seems that a CNAME (PUBLIC) pointing to another CNAME (in this case ZeroTrust’s public hostname) does not work (never mind the inefficiencies of double-cname-lookup: this is just for dev convenience).
Is that correct? Or am I doing something wrong?
Setup Recap:
A-DEV-SERVER: CNAME automatically created by ZeroTrust/Netwoks/Tunnels (i.e. the generated uuid name)
A-PROD-SERVER: A-record pointing to the real server’s IP address
PUBLIC: CNAME pointing to either A-DEV-SERVER OR to A-PROD-SERVER
- when PUBLIC points to A-PROD, all is well (hits live server)
- when PUBLIC points to A-DEV, get the 404
For context, I do this because in the future I’d like to simply change PUBLIC’s CNAME record to point to another CNAME (e.g. A-PROD-SERVER)
without having to change internal URLs (in various other systems).
So although all links will always point to PUBLIC the server that gets the request will be set as per that CNAME’s value.
This will give me flexibility to switch back and forth to either serving server with a single change
