DNS issues for certain customers - not sure how to fix

Hi,
I used to have the DNS and domain for my getadelante.com site and subdomain hosted by 1&1. I migrated the DNS to cloudflare last week, and it's now showing up as propagated.

However, some customers are still getting non-existent domain errors when accessing my site or subdomains - what can I dig into to try and solve it? it seems to be a subset of customers in the US that are behind a VPN/security tool. Once they disable the VPN/security limitations it normally works. Specifically, this customer is also using Cloudflare for their network management.

Thanks

As you're mentioning "customer"; - get the customer(s), that are having these problem(s) to also run:

nslookup -class=CHAOS -type=TXT id.server 1.1.1.1nslookup -class=CHAOS -type=TXT id.server 1.1.1.1
tracert 1.1.1.1tracert 1.1.1.1
nslookup -class=CHAOS -type=TXT id.server 8.8.8.8nslookup -class=CHAOS -type=TXT id.server 8.8.8.8
tracert 8.8.8.8tracert 8.8.8.8

And also report back with that information.

Is this trace from a different network, than the first screenshot you attached?
