What happened?
You’ve requested a page on a website (subdomain.example.com) that is on the Cloudflare network. Unfortunately, it is resolving to an IP address that is creating a conflict within Cloudflare’s system.
What can I do?
If you are the owner of this website:
you should login to Cloudflare and change the DNS A records for go2travel.modifly.shop to resolve to a different IP address.
I have set the record as a CNAME in the Cloudflare console but it is resolving as an A record:

That’s to be expected if the CNAME record is Proxied. This is Cloudflare’s CNAME flatening at play here: https://developers.cloudflare.com/dns/cname-flattening/
If your CNAME record is being flattened to a Cloudflare IP, that could mean the CNAME target provider is a Cloudflare customer.
Set the “Proxy Status” for this record DNS Only 
to see if that fixes the problem. If the problem persists or you see a different Cloudflare-branded error page, contact your hosting provider for assistance:
Thanks for the clarification and suggestions.
I have changed the domain to DNS Only, and the error is exactly the same. The dig results are strange though (domain names edited):
The DNS record is set as a CNAME for myexample.com, but when I resolve it using dig I get an IP that doesn’t correspond with the target domain:

Also, it is important to notice that there is a worker-route associated with this subdomain. And also important to notice that it is not the first setup as this I do on this domain, in fact, I have other ~30 subdomains with the exact same configuration and all work well, but not this one:
Thanks
