Please try these troubleshooting guides and let me know how it goes. They can solve most domain issues

https://vercel.com/docs/domains/troubleshooting

https://community.vercel.com/t/resolving-ip-blocking-issues/171

Thank you.

I have already completed most of the troubleshooting steps from the guide:

• Tested on multiple browsers (Chrome, Edge, Incognito)

• Tested with extensions disabled

• Tested on home internet and mobile internet

• Tested from another user in a different Russian region

• Tested using Google DNS and Cloudflare DNS

• Verified DNS configuration

• Verified Vercel domain configuration (Valid Configuration)

• VPN immediately resolves the issue

The problem reproduces consistently across different networks and users.

You mentioned the debug script and vercel-debug.txt output.

Could you please provide the exact debug script or instructions so I can generate and share the requested diagnostic information?

Thank you.

Additional information:

I contacted the domain registrar (Beget) and they confirmed that the domain is fully active.

The only WHOIS status is:

clientTransferProhibited

There are no clientHold or serverHold statuses on the domain.

We also performed additional testing:

• The issue reproduces for multiple users

• Different Russian regions

• Different ISPs

• Different mobile carriers

• Different devices and browsers

At the same time:

• portfolio-dimasik.vercel.app works correctly

• www.dmitrypod.tech times out without VPN

• VPN immediately resolves the issue

curl -v resolves the custom domain to:

• 216.198.79.65

• 64.29.17.65

Could you please verify whether there are any routing, edge network, or reachability issues associated with these IPs or with this specific custom domain configuration?

The evidence suggests this is not a local ISP issue and not a registrar/domain status issue.
