hi everyone, my website was published a few days ago, and it is operating fine. unti someone had to access it from enterprise network it was not accessibile for them. they’ve got DNS_PROBE_FINISHED_NXDOMAIN error messge on their broswer everytime they use their corporate devices. but it works fine from anyother device (personal, mobile)
have anyone face this before? any luck to overcome this issue?
Hi Abdelaziz,
Since it works from personal devices and mobile but fails only on corporate devices with DNS_PROBE_FINISHED_NXDOMAIN, I’d first treat this as a DNS resolution issue on the enterprise network, not a Vercel deployment problem.
Ask someone on the affected corporate network to compare the corporate resolver with a public resolver:
nslookup yourdomain.com
nslookup yourdomain.com 1.1.1.1
nslookup yourdomain.com 8.8.8.8
or:
dig yourdomain.com
dig yourdomain.com @1.1.1.1
dig yourdomain.com @8.8.8.8
What the results mean:
Corporate resolver returns NXDOMAIN, public resolvers return records
→ likely corporate DNS filter, DNS cache, split-horizon DNS, or security policy
All resolvers return NXDOMAIN
→ likely domain DNS/delegation is not configured correctly
Only www or only apex fails
→ check that both yourdomain.com and www.yourdomain.com are configured in Vercel/DNS
If only the enterprise DNS returns NXDOMAIN, the fix usually has to come from their IT/network team. They may need to clear DNS cache, allowlist the domain, or check whether a security product is blocking newly registered/uncategorized domains.
I would also ask them to test the exact domain you expect users to open, for example:
https://example.com
https://www.example.com
because apex and www can resolve differently.
